Perovskites make high-efficiency tandem solar cell

Researchers at Stanford University in the US and the University of Oxford in the UK have developed a new perovskite that can harvest infrared photons very well. When used together with another perovskite semiconductor that can harvest visible photons, the tandem device can covert solar energy into electricity with 20% efficiency. This figure could be increased to 30%, something that would revolutionize the solar industry………
