Perovskite layer fabrication and investigation of their optoelectronic properties for high efficiency tandem solar cells
Due to the constantly growing energy demand, accompanied by the depletion of organic fuel sources, global warming and related climate change, it is becoming increasingly urgent to search for renewable energy sources and improve them. One of the most promising and environmentally friendly energies is solar cell (SC) electricity.
Currently, about 80% of solar cells in the world are made of silicon. In order to reduce the cost of electricity produced by SC, it is necessary to either reduce the cost of SC or increase their conversion efficiency by improving and developing new technologies and materials. We propose to use tandem perovskite/silicon derivatives to increase the conversion efficiency of SC. The wide band perovskite layer located above the Si p-n junction would absorb high-energy quanta and thus reduce the negative influence of hot carriers on the formation of photovoltaics at the Si p-n junction, expand the effective absorption spectrum of solar radiation and at the same time increase the conversion efficiency of solar cells.
