快速热退火处理ZnO电子传输层对聚合物太阳能电池性能的改善
Enhanced Performance of Polymer Solar Cells Using Rapid Thermal Annealing Treated ZnO Electron Transporting Layer
摘要
Abstract
ZnO film was commonly used as electron transporting layer(ETL) in inverted polymer solar cell (IPSC) due to its excellent performance.Here, rapid thermal annealing(RTA) was applied to treat the ZnO ETL, and IPSCs with the structure of ITO/ZnO/PTB7∶PC71BM/MoO3/Ag were prepared.The ZnO films prepared under different annealing conditions were characterized by atomic force microscopy, scanning electron microscopy, X-ray diffraction ,UV-Vis-NIR transmission and photoluminescence (PL) spectra.The power-conversion efficiency (PCE) of IPSC using RTA treated ZnO as electronic transporting layer (ETL) is 8.1%, which is 11.26% higher than that of IPSC with ETL treated by traditional thermal annealing.The ZnO films treated by RTA have good crystalline properties, large grain size and rough surface, which decrease the series resistor (Rs) and increase the short-circuit current density (Jsc), fill factor (FF) of IPEC.关键词
