TiO2阴极缓冲层对 Rubrene/C70有机太阳能电池性能的改善
Improvement of TiO2 Cathode Buffer Layer to The Performance of Rubrene/C70 Organic Solar Cells
摘要
Abstract
To improve the performance of organic solar cells (OSCs) and enhance their stability in the air,the effect of TiO2 film as cathode buffer layer on the performance of OSCs was studied.The cells with a structure of ITO/TiO2/C70/Rubrene/MoO3/Al were fabricated.The influence of TiO2 on the cell was investigated by measuring the device efficiency.The experimental results show that the performance of cell is on the rise with the increase of the thickness of TiO2.when the thickness of TiO2 is 81 nm,the performance parameters are the best (power conversion efficiency current density,open circuit voltage and fill factor are 1.09%,2.55 mA·cm-2,0.88 V,48.69%,respectively),and the cell performance declines with the continued increasing of TiO2 thickness.Compared with the device without TiO2 layer,the optimal Jsc,Voc,FF and PCE of the cells increased by 37%,21%,17% and 91%,respectively.and the reasons for the improvement were discussed.关键词
