摘　　要：制备ITO/PEDOT∶PSS/PBDTC10BDT∶PC61BM/LiF/Al聚合物薄膜,研究了添加剂OT,DBrO对光敏层PBDTC10DBT∶PC61BM的影响,结果表明,加入微量的添加剂对光活化层的光吸收以及形貌起到积极的作用,添加剂的加入使得光活化层的分子排列更加有序,使各组分能够更好的吸收太阳光,同时光活化层的粗糙度减小,各组分之间的分布更加均匀,OT,DBrO的最佳添加量分别为2.5%和3%。当OT添加量为2.5%时,器件有最高光电转换效率1.93%。研究结果将为微相调节方法提高光伏器件性能提供理论依据和技术支持。The thin films of ITO/PEDOT：PSS/PBDTC10 BDT：PC61BM were fabricated. The effects of OT, DBrO additives on the PBDTC10 DBT：PC41 BM were investgated. The results show that trace amounts of additives play a positive role on the active layer in light absorption and morphology. Additives make Molecular arrangement of the active layer more orderly. Each component can absorb more sunlight. When the roughness of active layer reduces, the distribution of each component gets more homogeneous. The best addition amounts of OT and DBrO are 2. 5% and 3%. When addition amount of OT is 2.5 %, the energy conversion efficiency is the highest.
