Engineers from Stanford University used basic physics to improve solar panel efficiency. A transparent overlay made of patterned silica releases excess heat and cools down the panels. Excessive heat ...

Researchers have developed a quick and easy way to turn the wood-based bioproduct lignin into nanoparticles that can create a transparent coating with anti-fog properties or a colorful antireflective ...

The hotter solar cells become, the less efficient they are at converting sunlight to electricity, a problem that has long vexed the solar industry. Now engineers have developed a transparent overlay ...
