Solar cell parameters extraction, with less than 10 % error, refining the Co-Content function through an integration of a polynomial fit of I-Isc, in the case of constant percentage noise, and a percentage noise of the maximum current, Imax. Part 2: application to experimental current-voltage curves

Abstract In this article Part 2 of this series of articles, the methodology proposed in Part 1, namely, the fitting to a polynomial of the current minus the short-circuit current, i.e., \(I-{I}sc\), to calculate the Co-Content function \((CC(V,I))\) and extract the five solar cell parameters, i.e., the shunt resistance \(({R}ₛₕ)\), the series resistance \(({R}ₛ)\), the ideality factor \((n)\), the light current \(({I}lig)\), and the saturation current \(({I}ₛₐₜ)\), (within the one-diode solar cell model), is implemented on reported Current-Voltage (IV) curves found in the literature, both for laboratory made solar cells, as for and single-crystalline silicon (x-Si), multi-crystalline silicon (m-Si), cadmium telluride (CdTe), copper indium gallium selenide (CIGS), amorphous silicon (a-Si) tandem and triple-junction, amorphous silicon/crystalline silicon, heterojunction with intrinsic thin-layer (HIT), and amorphous silicon/microcrystalline silicon photovoltaic modules.
