CdSe量子点掺杂聚合物太阳能电池光谱响应特性研究

采用喷涂法分别制备了基于P3HT∶PCBM体异质结和P3HT∶PCBM∶QDs体异质结光活性层的有机太阳能电池器件,并对其光电响应进行了表征和对比。同时采用光谱手段对两者的光活性层进行对比分析。实验结果表明,量子点的加入拓宽了薄膜吸收光谱,同时增强了光致电子转移过程,从而改善了器件的光谱响应;双源共喷制备的P3HT∶PCBM∶QDs体异质结器件转化效率比同样是喷涂制备的P3HT∶PCBM体异质结提高了25%。

High efficiency bulk heterojunction organic solar cell by using high conductivity modified PEDOT: PSS as a buffer layer

In this paper,bulk heterojunction solar cells with poly-(3-hexylthiophene)(P3HT):[6,6]-phenyl-C61-butyric-acid-methylester(PCBM) as an active layer and modified poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)(PEDOT:PSS) as a buffer layer are fabricated.The buffer layer is modified by adding 1% to 5% dimethyl sulfoxide(DMSO) into PEDOT:PSS solution before spin-coating.The conductivity of modified PEDOT:PSS and the performance of solar cells with modified PEDOT:PSS are measured.The highest conductivity of modified PEDOT:PSS with 4% DMSO can achieve 89.693 S/cm.The performance of organic solar cell with PEDOT:PSS modified by 4% DMSO is the best.The 4% DMSOmodified-PEDOT:PSS cell has a power conversion efficiency of 3.34%,V oc of 5.7 V,J sc of 14.56 mA/cm 2 and filling factor(FF) of 40.34%.
