摘　　要：以P3HT作为电子给体材料,PCBM作为电子受体材料,制成不同厚度活性层的本体异质结有机太阳能电池.从I-V特性曲线分析了厚度对电池性能的影响.制备了添加PEDOTPSS和TiO2作为空穴阻挡层的有机电池,通过分析I-V特性曲线和吸收光谱,找到提高电池性能的方法.Organic solar cells made of P3 HT as electron donor and PCBM as electron acceptor with different thickness of active layer were fabricated and analysized. From the I-V characteristics of the devices,it was found that thickness of the active layer affected the efficiency of the device greatly. When blocking layer of PEDOT ： TiO2 were added to the device,it was found that different effect on the performance of the device characterized by I-V and adsorption analysis,the introduction of PEDOT ： TiO2 PSS improved the efficiency of the device while TiO2 did not change the performance evidently,further more a detail discussiou was involved.
