Description

technical field

[0001] The invention relates to the field of perovskite solar cells, in particular to the development of a class of hole-transporting polymer materials based on a triphenylamine-anthracene structure and its application in perovskite solar cells. Background technique

[0002] Since the solar cell was reported, it has gone through four development processes: the first generation is silicon-based solar cells represented by monocrystalline silicon and polycrystalline silicon; the second generation is based on cadmium telluride (CdTe) and copper indium gallium selenide (CdTe) CIGS) is a thin-film solar cell; the third generation is a solar cell represented by dye-sensitized (DSSC), organic (OPV) and quantum dots; the fourth generation is a new type of solar cell represented by a perovskite. As a new generation technology, perovskite solar cells are developing rapidly, and the photoelectric conversion efficiency has increased from 3.8% in 2009 to 9.7% in 2012 to ov...
