Scientists at Michigan State University have invented a new kind of solar concentrator. The material is transparent, so when positioned over a window, you can see through it. Apart from windows, this type of power-generating material could be placed over mobile device screens, or indeed over any other flat, transparent surface. To be sure, this [...]

Germany’s ongoing Energievende (energy transition) certainly has its critics. Some say that adding more renewable energy at a rapid rate will cause the heavily industrialized country’s electricity grid to become unreliable. However, so far it has turned out that the availability of electricity in Germany is more reliable than in the US, UK, Netherlands, and [...]

China has installed enough solar capacity in just six months to equal sunny Australia’s whole supply of solar power. China added 3.3 gigawatts of solar capacity in the 6 months to the end of June, which was double the figure from last year, China’s National Energy Administration has revealed. China now has a total of [...]

Spray-on solar cells are not new, but adequate efficiency has been somewhat lacking. Now, a team of scientists from the University of Sheffield are the first to manufacture more efficient peroviskite cells using a spray-painting process. Peroviskite is a promising new material for solar cells, and using it in the spray-painting process holds the potential to [...]
