主　　题：non-wetting dopant-free hole transport layer flexible solar cells large-scale 

摘      要：The regulated crystallization of perovskite and highly repeatable preparation are decisive challenges for large-scale flexible perovskite solar cells(PSCs).Herein,we synthesize an oil-soluble poly(3,4-ethylenedioxythiophene)(Oil-PEDOT)as a hole transport layer(HTL).The non-wetting Oil-PEDOT HTL can promote the quality of large-area flexible perovskite films because of its optimized crystallinity and *** Oil-PEDOT layer also delivers desirable conductivity and charge transport without a complex ***,the flexible PSCs with Oil-PEDOT HTL achieve an efficiency of 19.51%and 16.70%based on 1.05 and 22.50 cm^(2),***,these large-scale flexible PSCs demonstrate remarkable mechanical robustness,and the efficiency exhibits 93%retention after 7,000 bending *** results show that the Oil-PEDOT is a potentially efficient HTL for fabricating efficient large-scale flexible PSCs.
