Today, the Internet of Things (IoT) brings greater personalization and convenience to the devices that make managing our homes easier. This technology often results in tangled cables or batteries that need to be replaced regularly.

A solution to this problem could be to use solar panel technology in homes to power these smart devices. In a recent study, researchers revealed the most efficient photovoltaic (PV) systems among cool white LEDs, a common type of indoor lighting.

The difference between indoor lighting and sunlight

It is important to note that indoor lighting is different from sunlight. Light bulbs are dimmer than the sun and sunlight includes ultraviolet, infrared and visible rays, while indoor lights typically emit light from a narrower range of the spectrum.

Scientists have found ways to harness the sun’s energy using PV solar panels. However, these modules are not optimized for converting indoor light into electrical energy.

New generation PV materials

Some next-generation PV materials, including perovskite minerals and organic films, have been tested with indoor light, but it is not clear which are most effective at converting non-natural light into electricity.

Many studies use different types of indoor lights to test PVs made of different materials. Therefore, Uli cube and his colleagues compared different PV technologies with the same indoor lighting.

The results of the study

The researchers obtained eight types of PV devices, from traditional amorphous silicon to thin-film technologies such as dye-sensitized solar cells. They measured each material’s ability to convert light into electricity, first under simulated sunlight and then under cool white LED light.

Gallium indium phosphide PV cells showed the highest efficiency under indoor light. converts almost 40% of light energy into electricity.

As the researchers expected, the performance of the gallium-containing material under sunlight was modest compared to other materials tested due to its large band gap. A material called crystalline silicon showed the best effectiveness in sunlight but was average in indoor light.

Gallium indium phosphide has not previously been used in commercially available PV cells, but this study shows its potential beyond solar energy, the researchers say.

synthetic

However, they add that gallium-containing materials are expensive and may not be a viable mass-market product for powering smart home systems. In contrast, PV cells made from perovskite minerals and organic films are more cost-effective and do not present stability issues under indoor lighting conditions.

Additionally, researchers in the study found that some of the light energy generated indoors generates heat rather than electricity – information that will help optimize future PV systems to power indoor devices.

For better understanding

What is the Internet of Things (IoT)?

The Internet of Things (IoT) is the connection of devices or systems via the Internet that enables the exchange and collection of data. This includes everything from WiFi-connected home security systems to smart toilets.

What is Solar Panel Technology?

Solar panel technology uses photovoltaic (PV) systems to convert sunlight into electricity. These systems are typically used outdoors, but researchers have begun using them indoors to power smart devices.

Indoor light is generally weaker than sunlight and comes from a narrower range of the spectrum. For example, cool white LEDs, a common type of indoor lighting, do not emit ultraviolet or infrared light like the sun.

What are the new generation PV materials?

Next-generation PV materials include perovskite minerals and organic films. These materials have been tested with indoor light, but it is not clear which are most effective at converting unnatural light into electricity.

What are the advantages and disadvantages of different types of PV cells?

Gallium indium phosphide PV cells showed the highest efficiency under indoor lighting, converting almost 40% of light energy into electricity. However, these materials are expensive and may not be suitable for mass production. On the other hand, PV cells made of perovskite minerals and organic films are more cost-effective and do not have stability problems under indoor lighting conditions.

Main lessons

Summary

Photovoltaics (PV) is an attractive candidate to power the growing market for intelligent Internet of Things (IoT) devices such as sensors, actuators and wearables. Using solar cells and rechargeable batteries to power IoT devices helps eliminate costly disposable battery replacements and reduce environmental impact. IoT devices are often used indoors under artificial light, which differs from (outdoor) sunlight in that it has a much narrower, mostly visible spectrum, the intensity of which is typically 500 to 1000 times lower. In this work, the performance of state-of-the-art devices from eight different PV technologies (amorphous and crystalline silicon, copper-indium-gallium-selenide, cadmium-telluride, III-V, organic, dye and perovskite) are examined Conditions of identical interior lighting compared. Their performance in low illumination between 100 and 1000 lx is analyzed and the crucial importance of a sufficiently large parallel resistance is highlighted. Absorbent materials with larger band gaps exhibit lower thermalization losses and therefore achieve higher energy conversion efficiencies, consistent with theoretical expectations. The best device, an indium gallium phosphide solar cell with a band gap of 1.89 eV, showed a record efficiency of 39.9% under 500 lx of cool white LED light.

These guidelines are intended to help healthcare professionals identify people at high, medium or low risk and adjust treatment accordingly.

According to the authority, current variants of the virus tend to cause less severe disease than at the beginning of the pandemic. Vaccination increases immunity, which has led to a lower risk of serious illness and death in most patients.

Certain categories are no longer considered high risk

This update – the 13th since September 2020 – provides new estimates of the risk of hospitalization.

A new category, “intermediate risk,” now includes groups previously considered high risk, such as older adults and people with chronic illnesses, disabilities and comorbidities. Their hospitalization rate is estimated at 3%.

People with weakened immune systems continue to be at higher risk if they contract COVID-19, with an estimated hospitalization rate of 6%. According to the WHO, most people are in the low-risk category, with a hospitalization rate of 0.5%.

Always the same recommended medications

WHO continues to strongly recommend the antiviral drug nirmatrelvir-ritonavir, known by the brand name Paxlovid, for COVID-19 patients at high or intermediate risk of requiring hospital treatment.

If this drug is not available for high-risk patients, it is recommended to use molnupiravir or remdesivir instead.

The WHO also recommends against the use of molnupiravir and remdesivir in patients at moderate risk because the potential side effects outweigh the potential benefits.

It also does not recommend antiviral treatment for those at low risk of hospitalization and notes that “symptoms such as fever and pain can continue to be treated with analgesics such as paracetamol.”

The update also recommends against using a new antiviral, VV116, for COVID-19 patients except in clinical trials.

With the arrival of the MacBook Pro M3, a debate arises about the capacity of its 8 GB of RAM. Between Apple’s claims and experts’ doubts, where is the truth? Here are some tests to see more clearly.

The launch of the MacBook Pro M3 with 8GB of unified memory for 2000 euros has sparked a heated debate. Apple has defended this configuration, saying that 8GB on its devices is equivalent to 16GB on a standard PC. However, this statement is not unanimous in the tech community, as some consider the storage capacity to be insufficient, especially for a model that is considered an entry-level model.

Vadim Yuryev from YouTube channel Max Tech conducted an experiment by purchasing two M3 MacBook Pros, one with 8GB and the other with 16GB of storage, to compare their performance.

The performance difference is present in all tests

His tests showed clear differences at medium to high workloads. Especially when it comes to tasks like Cinebench rendering, merging photos in Photoshop, and exporting media to Final Cut and Adobe Lightroom Classic. The results showed a clear superiority of the 16 GB version.

Under these conditions, the performance gap widened even further, with crashes reported on the 8GB model during demanding operations such as Blender rendering and Final Cut export. These observations lead to a clear conclusion: For users with high performance needs, the 8GB of storage on the MacBook Pro M3 can be limiting.

The rest after this ad

Although enthusiasm for Fortnite has obviously waned since its launch in 2017, it is still the most popular and played battle royale today, especially since the return of the very first unconstructed map. Google once did everything it could to get Epic Games to publish and monetize Fortnite on its store, but it never succeeded…

An offer from Google that is difficult to refuse

Shortly before its release on mobile devices, the makers of Fortnite received an offer they could hardly refuse. As the lawsuit between Google and Epic Games confirms, the technology company offered $147 million to the owners of the Battle Royale. In return, they wanted the game to only be released on the official Android app store. It goes without saying that this amount was not enough to convince the developers and publishers of one of the most popular video games in history. For this reason, the two companies are now in a legal dispute.

Google used every mechanism at its disposal to convince Epic Games to launch (and monetize) Fortnite through the App Store, but was unsuccessful. Android officials disagreed with Epic Games’ decision to bypass its device’s terms of service and took actions that the company interpreted as a violation of U.S. competition laws. In this sense the reading is clear. Rejection of the aforementioned $150 million could change the history of video games – and apps – on mobile devices forever.

Reject 150 million euros to change the history of video games

If we stick to purely financial considerations, Epic Games seems to have made a good decision. Google’s plan called for a payment of $147 million over three years. A sum that would not have made up for what Fortnite’s parents lost by simply being in the store. In fact, the Android Store charges between 15 and 30% from developers for every transaction made through its systems. In this sense, the operation would have become profitable for Google (and loss-making for Epic) once BR raised between $500 and $1 billion on that platform. To give you an idea, before its first year on iOS, the game managed to reach the same $500 million in revenue (via SensorTower).

No one expected revenue from the mobile version of Fortnite to be this high, but Android executives feared two things. First, they estimated that the absence of Fortnite from the App Store could lead to a decrease in the store’s revenue by 150 to 250 million. But above all, they feared that this decision would be contagious. Other companies could take inspiration from Epic Games’ decision, which would lead to mounting losses over the years. If this possibility is confirmed, the shortfall would rise from $550 million to $3.6 billion.

As the end-of-year holidays approach, you will surely have to do a lot of shopping. And if you’re like the majority of people, you can assume that most of these purchases are made online. However, this practice is not without risks. In fact, the Internet exposes your personal information, including your banking information.

Your protection is therefore essential to avoid falling victim to hacker attacks. But rest assured, the process is very simple: all you have to do is use a VPN. And the best you can find in this area is NordVPN, which we present to you below.

Ultimate online security from NordVPN

Why choose NordVPN to protect your online purchases? For many reasons. The first is that this editor secures your connection on multiple levels. On the one hand, it creates a VPN tunnel around your connection, protecting the data within it. On the other hand, your IP address is completely hidden, which also exposes a lot of personal information.

This completely anonymous surfing prevents you from becoming a victim of hacker attacks, espionage or even theft. But NordVPN goes even further. A second reason why you should choose it for your online security (especially your purchases) is that it offers a variety of advanced options. As examples we can name the Kill Switch, the Double VPN or the provider’s own threat protection.

Third valid reason: NordVPN is 100% no-log. This means that no information about you or your online activities is stored, ensuring increased privacy. And currently, NordVPN is releasing a preview of its special Black Friday offer. This includes a 63% discount and 3 free months on the 2-year plan. So you can subscribe for 27 months at the preferential price of €80.73, which is just €2.99 per month.

Protect your purchases with NordVPN

And all of this without any technical manipulation

If you’ve never used a VPN before, you might be hesitant about getting such software. But don’t worry: NordVPN is very easy to manipulate. To install it you just need to download it from the official site or from your usual application store. You can then immediately identify yourself and use it.

Clicking on the desired server or on the “Quick Connect” option activates the tool. You are now protected and all you have to do is browse as usual and leave the VPN running in the background. The settings are also simple and accessible and NordVPN allows you maximum flexibility.

The software can be installed on computers (Windows, macOS, Linux), but also on smartphones and tablets (iOS, Android). NordVPN is even compatible with major smart TVs and most popular connected boxes. It also fits on the router. Additionally, a subscription with this provider gives you access to 6 simultaneous connections as well as 24/7 technical support. So you can try it without any fear

Try NordVPN

With optimal freedom of navigation as a bonus

If you’ve ever researched VPNs, then you may have found that many internet users use them to access new content. And this is actually possible for you with NordVPN. The provider has more than 5,800 servers worldwide. These cover a total of 60 countries to give you maximum choice.

But how exactly does it work? Since NordVPN allows you to connect to all of these areas, you can actually change your IP address. You can therefore change your perceived location online as it is your IP address that gives it away. You understood the rest: by changing your virtual location, you can fool the geolocation systems of the targeted content and unblock third-party programs.

This works in particular with Netflix, but also with the main IPTV channels (the best VPNs for IPTV) as well as for game servers or websites, among others. For greater efficiency, NordVPN even has high-speed obfuscated servers and unlimited bandwidth.

And all of this is included in the publisher’s current offering. Remember, NordVPN is one step ahead of Black Friday with a 63% discount and a 3-month offer for the 2-year subscription. You can therefore subscribe for €80.73 for 27 months (€2.99 per month) and benefit from a 30-day money-back guarantee.
