In your home, you probably have a handful of gadgets that rely on batteries: remotes, smoke detectors, wireless keyboards. But instead of having to replace those batteries again and again, those ...

Perovskite solar cells have gained a lot of attention in research circles recently owing to significant and relatively fast leaps in its efficiency, but the toxic lead they contain is something ...

Conventional solar cells are just that: photovoltaic devices which, by their physics, extract and transform energy from the sun. Their sensitivity and efficiency are matched to the optical-energy ...

From Wi-Fi-connected home security systems to smart toilets, the so-called Internet of Things brings personalization and convenience to devices that help run homes. But with that comes tangled ...

In a world where billions of connected devices—from smart thermostats to wireless sensors—demand small amounts of energy, battery replacements have become a wasteful and costly habit. Scientists from ...

Solar power is an increasingly mainstream technology, and you can now get solar chargers for your phone, solar-powered clothes, and rollable solar panels. But most of us spend most of our time indoors ...

As compared to their more commonly-seen counterparts that utilize crystalline silicon semiconductors, organic solar cells are thin, flexible, lightweight and cheap, allowing for their application in a ...

In a future where most things in our everyday life are connected through the internet, devices and sensors will need to run without wires or batteries. In a new article in Chemical Science, ...

Scientists have invented a new kind of solar panel capable of harvesting energy from indoor fluorescent lights. The next-generation solar cells were created using the so-called ‘miracle material’ ...
