The storage stability of ETL/POLYMER A based PSCs was enhanced significantly as compared to the ETL based PSC, while the PV performance was similar to that of the ETL based PSC. The enhancement of storage stability was attributed to the higher hydrophobicity and moisture resistance of ETL/POLYMER A layer. On the other hand, PV performance of ETL/POLYMER P based PSCs was slightly enhanced as compared to the ETL based PSC, while the storage stability was decreased for the former. The presence of POLYMER P promoted the electron-transporting capacity of ETL based interfacial layer and resulted in the higher current density and photo-conversion efficiency of PVCs. However, higher hydrophilicity of POLYMER P resulted in the poor storage stability of ETL/POLYMER P based PSCs.
