Influence of Cesium Chloride Methanol Solution on The Conventional Organic Polymer Solar Cells
摘要
Abstract
The cesium chloride ( CsCl) methanol solution was introduced into the conventional or-ganic polymer solar cells as cathode buffer layer to improve its properties. The charge accumulation between the Al cathode and PTB7/PC70 BM was analyzed through capacitance-voltage ( C-V) meas-urement and the change of work function of Al was investigated by ultraviolet photoelectron spectros-copy (UPS). The results show that the short-circuit current (Jsc), the open-circuit voltage (Voc), the fill factor and the power conversion efficiency ( PCE) of the device with the CsCl methanol solu-tion treatment have been improved. And the PCE reaches 6. 36%, which has been improved 11%compared with the methanol treatment devices and 42 . 6% compared with the devices without any treatment. This one-step solution treatment can improve the device properties by reducing the charge accumulation and decreasing the work function of Al cathode which is benefit to electron collection.关键词
