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.

Investigation of the Performance of CIS Photovoltaic Modules under Different Environmental Conditions

“…The shunt resistance, R sh , represents a parallel high conductivity path across the p-n junction or the cell edges and decreases the efficiency of the cells by increasing the leakage current that lowers the maximum output power (P m ), the open voltage, V oc and the fill factor, FF. Several methods are available in the literature for extracting the series and shunt resistances of a solar cell [1][2][3][4][5][6][7][8][9][10][11][12] as well as related device parameters. Some of the methods involve measurement of illuminated I-V characteristics, some use dark conditions or utilize dark and illumination measurements.…”

Influence on open-circuit voltage by optical heterogeneity in three-dimensional organic photovoltaics

“…The gray curve is fitted by Eqn. (3) in which all the parameters of devices are extracted from IV curve in terms of an iterative method 37 . Then, we apply this principle into the tube-base cell (sample B), which were prepared by a dip coating method.…”

“…In most common distribution, 2a(b+μ)>>σ for most device parameters 37 , therefore V oc -V oc-homo~0 . Consequently, the total illumination, whether homogenous or heterogeneous illumination has the same functional effect on voltage.…”

Tandem Solar Cells Based on Cu2O and c-Si Subcells in Parallel Configuration: Numerical Simulation

“…The ideal working conditions for tandem are defined. The single-diode model for solar cells is used [16]. The parameters of the subcells and tandem are calculated from the maximum condition of the output power.…”
