The FAQ You’ve Always Had About Supercapacitors
Are batteries and supercapacitors interchangeable? Although both batteries and supercapacitors are energy storage devices, they have different properties that allow them to serve different functions. The main properties of interest when looking at energy storage devices are the specific energy (Wh/L) and specific power (W/L). Specific energy determines the amount of energy that can be stored in ...

Idea could lead to cheap solar cells using plant waste
Remote communities could eventually make their own solar cells using waste vegetation, thanks to a design developed by researchers in Switzerland and the United States. The technology is inspired by photosynthesis. In plant cells, sunlight separates electrical charges with almost 100 per cent efficiency. Electrical charges must also be separated to create currents in solar cells. For the past ...
