Cs_0.05(MA_0.17FA_0.83)_0.95Pb(I_0.83Br_0.17)₃, which has been reported to exhibit high photoelectric conversion efficiency and excellent stability, was fabricated using a bar coating method applicable to large-area production. The film coverage improved with increasing substrate temperature during film formation, and the thinnest and smoothest films were obtained at a coating bar sweep speed of 4.0 mm/s. Although PbI₂ was generated by the thermal treatment after film formation, the exclusion of the thermal treatment prevented the formation of PbI₂. The characteristics of solar cells fabricated under optimal conditions were compared with those of MAPbI₃.
