Comparative study between two electrical model using experimental IȃV curves for DSSCs prepared by electrophoretic technics

Abstract

Photovoltaic solar cells are non-linear devices, whose modeling is not an easy task. Different models for solar cells are available in the literature. Dye-sensitized solar cells (DSSCs) are considered as third photovoltaic generation and are proposed as alternative to conventional silicon solar cells. They have numerous advantages over silicon based solar cells such as low materials cost and simplicity of production methods. In this work we present studies on the DSSC fabricated by electrophoresis deposition techniques (EPD) and sensitized by several natural dyes. Comparative study between two Pspice electrical models using four and five parameters has been investigated using experimental results deduced from I-V curve. The obtained parameters are used as Pspice input data to simulate the I-V curve for the two models. The results show that the four parameters model is in agreement with the experimental results.
