A Numerical Model and a Code Development for Photogeneration Rate Calculation for a Dye Sensitized Solar Cell

Dye Sensitized Solar Cell (DSSC) is an excellent option for the future energy supply because it provides outstanding promise in delivering a low-cost, easy manufacturability. For a deeper understanding of the mechanisms of the DSSCs, the modelling and simulation are required. In this paper, the development of a MatLab code is presented which is able to calculate the photogeneration rate in function of the cell thickness. The operation of the code is illustrated through an example, two different DSSCs were used for, proving and providing that the code works. The MatLab code is based on different equations of photo electrochemical in the Dye Sensitized Solar Cell. Based on solving the photogeneration rate, the model uses the numerical finite-element method. In accordance with the studied literature, the presented code has not been used before. The results also highlight that the photogeneration rate in function of the cell thickness of the cell depends on the optical parameters of the sensitized dye.
