用CdSe/ZnS量子点提高体异质结有机太阳电池的效率
To Improve the Efficiency of Bulk Heterojunction Organic Solar Cells by Incorporating CdSe/ZnS Quantum Dots
摘要
Abstract
The efficiency of bulk heterojunction solar cells was enhanced by incorporating CdSe/ZnS core-shel col oidal quantum dots (CQDs) into copolymers of poly(3-hexylthiophene (P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) as the active layer, as result of the increased absorption in the visible region. The doping of CdSe/ZnS CQDs in the active layer and the influence of CQD surface ligands on device performance were investigated. A maximum power conversion efficiency (PCE) of 3.99% was obtained from the optimized solar cellITO/PEDOT:PSS/P3HT:PCBM:(CdSe/ZnS)/Al (ITO:indium-tin oxide;PEDOT:poly(3,4-ethylendioxythiophene;PSS:poly(styrenesulfonate)) under AM1.5 il umination. This was 45.1%improvement on the PCE of the control device ITO/PEDOT:PSS/P3HT:PCBM/Al.关键词
