This study applied a one–step method to prepare planar organic–inorganic hybrid heterojunction perovskite solar cells and adopted anisole, phenetole, benzyl methyl ether, and butyl ether as anti–solvents for the first time. The effects of the four anti–solvents on the performance of the perovskite thin films and the corresponding cells were investigated. In addition, the quality of perovskite thin films and the performance of cells prepared with the four anti–solvents were compared to those of cells prepared with the diethyl ether which is the most commonly used anti–solvent. The research results indicate that the surfaces of the perovskite thin films formed with benzyl methyl ether and butyl ether as anti–solvent are rough and have many voids. The weak diffraction peaks of the corresponding perovskites indicate relatively poor crystallinity. The perovskite thin films obtained using phenetole as the anti–solvent have pinholes. The perovskite thin films obtained using anisole as the anti–solvent are uniform and dense and have good crystallinity. These were compared to the perovskite cells that use diethyl ether as the anti–solvent; the open–circuit voltage increased from 1.06 V to 1.09 V; the fill factor is enhanced from 65% to 76%; the power conversion efficiency is improved from 14.53% to 16.73%, and the perovskite cell has good reproducibility.

W badaniu zastosowano jednoetapową metodę przygotowania płaskich, organiczno-nieorganicznych, hybrydowych, heterozłączowych perowskitowych ogniw słonecznych i zastosowano po raz pierwszy anizol, fenetol, eter benzylowo-metylowy i eter butylowy. Zbadano wpływ czterech przeciwrozpuszczalników na osiągi cienkich warstw perowskitu i odpowiednich komórek. Ponadto jakość cienkich warstw perowskitu i wydajność komórek przygotowanych za pomocą czterech przeciwrozpuszczalników porównano z komórkami przygotowanymi za pomocą eteru dietylowego, który jest najczęściej stosowanym przeciwrozpuszczalnikiem. Wyniki badań wskazują, że powierzchnie cienkich warstw perowskitu utworzonych z eteru benzylometylowego i eteru butylowego jako przeciwrozpuszczalnika są szorstkie i mają wiele pustek. Słabe piki dyfrakcyjne odpowiednich perowskitów wskazują na stosunkowo słabą krystaliczność. Cienkie warstwy perowskitu otrzymane przy użyciu fenetolu jako przeciwrozpuszczalnika mają otwory. Cienkie warstwy perowskitu otrzymane przy użyciu anizolu jako przeciwrozpuszczalnika są jednorodne i gęste oraz mają dobrą krystaliczność. Zostały one porównane z komórkami perowskitu, które wykorzystują eter dietylowy jako przeciwrozpuszczalnik; napięcie w obwodzie otwartym wzrosło z 1,06 V do 1,09 V; współczynnik wypełnienia został zwiększony z 65% do 76%; wydajność konwersji mocy została poprawiona z 14,53% do 16,73%, a ogniwo perowskitowe ma dobrą odtwarzalność.
