摘要：

Screening green solvents to prepare the functional layers in perovskite solar cells (PSCs) is important for the safety of manufacturers and the environment in the upcoming large-scale industrialization. The all-green solvent engineering of perovskite films aims to eliminate the toxicity that is caused by the traditional host solvent and anti-solvent. However, it still needs the highly toxic solvent of chlorobenzene (CB) to prepare the hole transportation layer (HTL) of spiro-OMeTAD films to achieve high-performance solar cells. In this work, we screened the green solvent of anisole to replace the highly toxic CB to prepare the spiro-OMeTAD films in typical solar cells. As a result, we achieved fully green solvents for the fabrication of all functional layers in the most attractive PSCs with a configuration of FTO/SnO2/(FAPbI3)0.95(MAPbBr3)0.05/spiro-OMeTAD/Au. The best solar cell delivers a power conversion efficiency (PCE) of 19.0%, which is comparable to the toxic CB processed HTL layer in PSCs. This work provides a candidate of choice to achieve fully green solvents for all functional layers in high-performance PSCs. Green solvent processing of all the functional layers in efficient solar cells.
