An effective method for simulation and estimation of dye-sensitized solar cells parameters

Abstract

A computer simulation and calculation method has been proposed in this paper to provide an effective and simple way to estimate the five parameters of dye-sensitized solar cells including photocurrent, reverse saturation current, diode ideality factor, series resistance and parallel resistance of the output characteristic equation. The computer program which was used to calculate these parameters automatically was written in the VB compiler environment. With the program we can get five parameters within several seconds and the maximum error is only about 5.6% which is much smaller than those gotten by computer simulation methods until now. Combining with practical experiment, this method was proved to be an effective and quick way to get the five parameters of DSSC and can aid to analyze their influence to the output V-I characteristics.
