Abstract

An analytical model of the photocurrent-voltage characteristics has been utilized to analyze important properties of organic bulk-heterojunction solar cells, e.g., generation rate, electron current density, hole current density and the total photocurrent density. The generation rate of P3HT:PCBM based solar cell critically depends on the absorption coefficient. For measuring the electron and hole current density solution of carrier continuity equation is used in MATLAB. Then the effects of electron and hole current density on the performance of P3HT solar cells have been studied. The result of this paper demonstrate that current density due to electron plays a major role in photocurrent production while hole current density has a very little impact. Effect of electron and hole mobility variation are investigated separately which indicate that increasing electron mobility are extremely important than hole mobility to increase the power conversion efficiency of P3HT:PCBM blend. The dependence of electron and hole current densities as a function of the blend thickness is also analyzed.

基于P3HT:PCBM的有机太阳能电池性能分析

利用光电流-电压特性的解析模型分析了有机体异质结太阳能电池的重要特性，如产生率、电子电流密度、空穴电流密度和总光电流密度。P3HT:PCBM基太阳能电池的发电速率主要取决于吸收系数。为了测量电子和空穴电流密度，利用MATLAB求解载流子连续性方程。然后研究了电子和空穴电流密度对P3HT太阳能电池性能的影响。结果表明，电子产生的电流密度对光电流的产生起主要作用，而空穴电流密度对光电流的产生影响很小。分别研究了电子迁移率和空穴迁移率对P3HT:PCBM共混物功率转换效率的影响，结果表明提高电子迁移率比提高空穴迁移率更为重要。分析了电子和空穴电流密度随共混厚度的变化规律。
