摘　　要：基于简单的溶剂注射工艺制备了PbSe纳米晶，利用平均粒径为5nm的PbSe米晶制备了P3HT／PbSeeh,P3HT／PbSe／PCBM两种结构的纳米晶聚合物太阳能电池，P3HT／PbSe电池的最高光电转换效率为O．19％，而基于三相体系P3HT／PbSe／PCBM池的光电转换效率为2．09％，说明PCBM对提高电池的光电转换效率具有重要的作用。The narrow bandgap nanocrystal has become one of the promising alternatives for application in solar cells due to its novel absorption ability in near infrared area and its convenient properties for charge transportation. However,the photovohaic performance of the solar cells based on nanocrystals is still poor compared with that of the conventional silicon solar cells. Based on the facile solvent injection method,high quality PbSe nanoerystals were synthesized under nitrogen atmosphere. Based on the highly crystallized PbSe nanocrystals,inverted hybrid solar cells that composed of P3HT/PbSe and P3HT/PbSe/PCBM were investigated. Through process optimization,the PCE of 0.19% was obtained for P3HT/PbSe solar cells. The PCE of 2.09% was obtained for P3HT/PbSe/PCBM solar cells,which is much higher than that of P3HT/PbSe solar cells.
