A team of researchers working at Oxford University has found a way to add cesium to perovskite solar cells to boost the performance of [silicon, while maintaining the efficiency benefits it offers. In their paper published in the journal Science, the team describes their process which included finding a way to overcome the problem of efficiency loss in such materials that normally come about due to a limited range of solar spectrum use.

As researchers around the world continue to look for the next-generation material to use for solar power collection to increase efficiency, others continue to seek ways to improve the standard now in use: silicon.
