摘　　要：利用AMPS-1D软件研究以富勒烯衍生物(PCBM)作为电子缓冲层的有机太阳能电池微观机理。研究结果表明,添加PCBM材料作为器件的电子缓冲层,能减小空穴-电子的复合率和提高空穴-电子的寿命,进而提高有机太阳能电池开路电压、短路电流密度、填充因数以及光电转化效率。PCBM材料的厚度对开路电压影响较小,但器件的短路电流密度随着PCBM厚度的不断增加有明显的提高。It was studied the electron microscopic mechanism of heterojunction organic solar cells based on PCBM electronic buffer layer by AMPS-1 D software.The results showed that it could reduce hole-electron recombination rate and improved the life of hole-electron by adding PCBM material as a device of electronic buffer layer.Whence the open circuit voltage,short circuit current density,fill factor and the photoelectric conversion were efficiency improved.The effect of thickness of PCBM material on the open circuit voltage was small.But the short circuit current density of device was obvious increased with increasing PCBM thickness.
