Perovskite Solar Cells: Ground Breaking Discovery which will lead to increase in stability and efficiency
Perovskite has been hailed for its remarkable properties compared to traditional silicon solar cells, however, until now they have been too unstable to be suitable for commercial use. The next-generation cells are expected to cost less, have a much higher power conversion efficiency, and be lightweight and flexible – opening up new applications like coating glass windows with thin layers of solar panels. A team of researchers from the city university of Hongkong and Imperial College, London has made this ground-breaking discovery. The chemists were able to overcome perovskite’s difficult properties by making use of a metal-containing material called ferrocenes, which they added as an interface between the light-absorbing layer of the solar cell and the layer that transports electrons. The unique properties of ferrocenes can help overcome the problems with perovskite solar cells,” said Professor Nicholas Long from Imperial Co...
