Professor Shanhui Fan and a team at Stanford University have built what they call “moonlight panels,” devices that generate electricity after the sun goes down by exploiting the temperature difference ...

On a global level, solar energy has grown exponentially over the last few decades as costs have plummeted and demand has risen accordingly. It is estimated that the world added a third more solar ...

Perovskite semiconductors efficiently convert sunlight into electrical energy; they are also inexpensive and extremely ...

Perovskite solar cells shouldn’t work as well as they do—but they do. Scientists have now discovered that defects inside the material actually help, creating networks that separate and guide electric ...

A promising solar-cell architecture, in which two layers of perovskite semiconductors are stacked on silicon, is making strides towards achieving its full potential. Read the paper: Triple-1 junction ...

Researchers have developed a perovskite-organic tandem solar cell that achieves 26.4 percent efficiency. Unlike rigid silicon modules, the lightweight design can generate power on curved or flexible ...

A new solar breakthrough may overcome a long-standing efficiency barrier. Researchers used a “spin-flip” metal complex to capture and multiply energy from sunlight through singlet fission. The result ...

Does adding a new home solar panel system makes sense in northern climates? This Canadian homeowner did just that – and after a cold, dark, and dreary winter collecting data, they’re sharing their ...
