Simulation of polymer-fullerene bulk heterojunction solar cell

A numerical model of organic bulk heterojunction solar cell based on Onsager's theory of geminate charge recombination and related theory of inorganic semiconductors is described. the correctness of the model is verified by experimental data. On the basis of this model, we analyzed the influence of effective voltage and operating temperature on the properties of organic solar cells and the factors that affect the photocurrent efficiency of the device.
