Complex halides of antimony and bismuth for use in solar cells.
Technology is in the process of development!
Complex halides of antimony and bismuth for use in solar cells:
Scientists have created new semiconducting materials on the basis of complex halides of antimony and bismuth (i.e. compounds of antimony and bismuth with fluorine, bromine, chlorine or iodine) for use in solar batteries as solar cells to convert solar light into electrical current. An example of such a material is a material with the chemical formula ASbBr6 (where A is an organic positively charged ion). These semiconductor materials have a cubic structure, similar to the structure of the mineral perovskite (calcium titanate, CaTiO3), so that they have high conversion efficiency of light. Also they are characterized by low cost and ease of manufacture.
