An extensively valid and stable method for derivation of all parameters of a solar cell from a single current-voltage characteristic

Abstract

It is important to precisely estimate values of all solar cell parameters in order to analyze the performance of a solar cell. We have proposed a stable method for the derivation of solar cell parameters from a single I-V curve under only the valid assumption for a general solar cell. Our method was applied to experimental I-V curves of a selection of solar cells, comprising of silicon, organic, and dye-sensitized solar cells, which were previously reported. Each I-V curve was calculated using the values of parameters derived from our method, and was found to be in good agreement with the experimental I-V curves, compared to previous work. Our extensively valid and stable method can be applied to for the analysis of all kinds of solar cells showing various characteristics that follow the single diode model and is very useful for improving the performance of developing solar cells. © 2008 American Institute of Physics.
