摘要：

We demonstrate an enhancement in the power conversion efficiency (PCE) of p-i-n type organic solar cells consisting of zinc phthalocyanine (ZnPc) and fullerene (C(60)) using a p-layer of palladium phthalocyanine (PdPc). Solar cells employing three different device structures such as ZnPc/ZnPc:C60/C(60), PdPc/PdPc:C60/C(60), and PdPc/ZnPc:C60/C(60) with varying thickness of mixed interlayers were fabricated by thermal evaporation. The mixed i-layers were deposited by co-evaporation of MPc (M=Zn, Pd) and C(60) by 1: 1 ratio. PCE of 3.7% was obtained for optimized cells consisting of PdPc/ZnPc:C(60)/C(60), while cells with device structure of ZnPc/ZnPc: C(60)/C(60) showed PCE of 3.2%.
