At the beginning of 2016, science magazine published a new study, researchers at the University of Cambridge have developed a synthetic material called mixed lead halide perovskite, set off a wave in the technical field of solar cell. This material can absorb sunlight, create a charge carrier, and then can produce some of their own electricity.
Felix, of University of Cambridge, Deschler, said: "we already know that these materials are good at absorbing light and producing charge carriers. But now the experiment shows that this material can be re - generated photons. And making this kind of battery is cheap and easy to make, making it more commercial."
Solar cells convert solar energy into electricity by absorbing solar photons, which convert them into electricity. Hybrid perovskite lead halide can not only do these, also show more ability in the creation of charge: perovskite can actually self luminous and then absorbed light.
Deschler said: "the efficiency of the current recording of the photon is 20%-21%, and the absolute upper limit is 33%. Our results show the way to achieve this limit."
The research has attracted the attention of many solar cell manufacturers, seeking to find a cheaper and more effective way to absorb sunlight. more solar batteries like:
