Abstract

We apply three different mobility models named exponential model of Pai, mobility edge model with single Gaussian DOS, and double Gauss model to one organic diode with polymer poly(3-hexylthiophene) (P3HT). These three models are different from one another with respect to their function. The results obtained from three different models are well explained in this paper by acquiring the suitable parameters, and gives satisfactory results. When the parameter and results of these models are compared with one another the modified double Gauss model agrees well with the current voltage data. While exponential model of Pai and mobility edge model with single Gaussian DOS shows the abnormality condition in mobility range.
