Simulation of the Electrical Parameters of Organic Photovoltaic Cells

This work represents the modelling and simulation of organic solar cells using Quite Universal Circuit Simulator, QUCS. An equivalent circuit model constituted from one diode, a series and shunt resistance, and a photocurrent generator have been used. The simulated results as function of different parameters such as series resistance, temperature of the cell, the ideality factor and current saturation are given. The current density as function of voltage J-V characteristics of the organic cell obtained from the experimental results are compared to the simulated one, a value of 1.2 of the ideality factor is established.
