The Numerical Analysis of Organic Solar Cells Based on Buffer Layer of ZnO

氧化锌(ZnO)材料具有良好导电性、光透性和稳定性,在光电器件中具有重要用途.利用AMPS-1D探究ZnO作为缓冲层对有机太阳能电池性能的影响.研究发现:添加ZnO缓冲层的有机太阳能电池开路电压、光电转化效率等性能有显著的提高; 电子-空穴产生率和空穴电流密度随着ZnO薄膜厚度增加而减小,而电荷态密度和电子电流密度随着ZnO薄膜厚度增加而增大.
The material of ZnO has good conductivity,light permeability and stability,so it is important to use in optoelectronic devices.The performance of organic solar cells with ZnO as a buffer layer is explored by using AMPS-1D.The study is found that open circuit voltage,photoelectric conversion efficiency,etc.have improved significantly by adding ZnO buffer layer of organic solar cell.The electrons-hole rate and current density of holes increases with decreasing of thin film thickness of ZnO,but the charge state density and electron current density increases with increasing of thin film thickness of ZnO
