CdSe量子点掺杂聚合物太阳能电池光谱响应特性研究
Research on Spectral Response of CdSe Quantum Dots Dopted Polymer Solar Cell
摘要
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%。
Abstract
In the present paper, bulk heterojunction polymer solar cells based on P3HT∶PCBM and P3HT∶PCBM∶QDs active layer were fabricated and measured respectively. The experimental result showed that the addition of QDs can broaden the spectral response and enhance photoinduced electron transfer. The conversion efficiency of device with QDs is about 25% higher than that without QDs.
