Abstract

In this paper, a series of antisolvent ethyl acetate （EA） and acetonitrile （ACN） were added to the perovskite precursor to prepare CsPbBr₃ thin films with different morphologies, and the effect of thin film quality on the performance of perovskite solar cells was studied. Research results show that in the atmosphere preparation environment, the antisolvent can promote the growth of CsPbBr₃ grain, the surface defects of the film are significantly reduced, and the short circuit current density, open circuit voltage and filling factor of the prepared FTO/TiO₂/CsPbBr₃/Carbon structure solar cells are improved. In particular, when acetonitrile （V（PbBr₂/DMF）∶V（ACN） is 10∶1） was added, the solar cell photoelectric conversion efficiency （PCE） was increased from 3.16% to 7.10%.
