Jelly solar cells
Solar cells are traditionally made from high purity semiconductor materials, such as silicon. Their production requires high temperatures and ultra-clean environments, which makes them expensive. The resulting structure of the material is extremely ordered and rigid. A novel class of solar cell materials has recently been discovered. These materials are called hybrid perovskites. They have the same efficiency for converting light into electricity as the traditional semiconductors, but do not rely on the same expensive production process. This favourable combination has attracted many scientists to this material over the past decade.
