Perovskite materials can be made into solar power generator, photovoltaic conversion efficiency is high, in recent years, the scientific community has been optimistic about its prospects. But it also has the performance is not stable, easy to decay the flaw, has not been mature product. Australian National University Australian National University (ANU) the researchers developed a new fabrication process of perovskite, and include indium and other elements, which greatly enhance the efficiency of the solar cell and a series of perovskite perovskite - silicon solar cell. Compared with the current silicon solar cell materials, the perovskite material is thinner, flexible, and cheaper.
The research team in the United States this year has developed a new solar generator, consists of two series of all perovskite solar cells, with 20.3% of the overall efficiency of solar energy into electrical energy, the photoelectric conversion efficiency is close to now on the market of silicon solar cells. The ANU researchers further enhance the efficiency of the series of perovskite solar cells, in the production process of the mixture of indium materials, further making the series of perovskite cell efficiency.
Research team leader Tom White said, only need to add additional process steps in the production of monocrystalline silicon solar cell production line series of solar backup generator, titanium silicon solar maximum can be between the solar energy conversion efficiency up to 25%-30% production, is higher than that of single battery.
