摘要	PH1000/graphene (Gra) composite film with thermally-induced wrinkles has been employed as an electrode in organic solar cells (OSCs) to enhance the device efficiency. The wrinkled PH1000/Gra composite electrode exhibits excellent transmittance of 88.5% at 550 nm, decreased sheet resistance of 147.5 Omega sq(-1) and appropriate work function of similar to 4.9 eV compared to pristine graphene. OSCs with wrinkled composite electrode possess enhanced short circuit current (J(SC)) compared to that of planar devices due to the wrinkles-induced enhancements in light absorption and charge collection. The power conversion efficiency (PCE) of OSCs with wrinkled composite electrode is 4.67%, which is 60% or 35% higher than that of planar devices based on the pristine graphene (2.93%) or PH1000 (3.45%) electrode, respectively. Corresponding PCE is comparable to that of the conventional ITO-based OSCs (5.08%). Even better, flexible OSCs with PH1000/Gra composite electrode exhibited excellent mechanical stability compared to ITO device. The enhanced efficiency of the OSCs demonstrates that the wrinkled PH1000/Gra composite electrode is a promising candidate for efficient and flexible optoelectronic application.
