Two-step Precise Determination of the Equivalent Circuit Parameters for Dye-sensitized Solar Cells

摘要：

Analyzing the equivalent circuit models for solar cells is a fundamental research topic in developing high-performance photovoltaic devices. Here we demonstrate a two-step method to determine all the five equivalent circuit parameters for dye-sensitized solar cells with high accuracy. With the five parameters extracted from the graphic method as the initial values, the accurate values of the five parameters are obtained by Non-linear least squares fitting. The accuracy of the two-step method is validated by fitting several I-V characteristics of dye-sensitized solar cells from both our experimental results and other research groups, and the root mean square errors for all the fitting results are less than 1 ％.
