Modelling and simulation of the electrical parameters of DMSO doped PEDOT: PSS/n-Si organic/inorganic solar cells using the Lambert W function

In this work, we present an analytical method based on three diode model to estimate the electrical parameters of the hybrid photovoltaic solar cells. The photovoltaic module is generally represented by an equivalent electrical circuit whose electrical parameters are determined experimentally using the current density -voltage (J -V) characteristic in dark and under illumination. The current-voltage characteristic obtained according to Kirchhoff's law applied to the equivalent circuit using to study the doped PEDOT: PSS/n-Si hybrid photovoltaic solar cells with various dimethyl sulfoxide (DMSO) concentration is resolved numerically by applying the Lambert W function. The parameters extracted which key parameters for the hybrid photovoltaic solar cells which are shunt resistance (Rs), series resistance (Rsh), ideality factors (n1, n2, n3), saturation current density Jsi (i = 1,2 and 3) and generated current density (Jph) are determined and compared with those calculated by the model. The results of numerical simulations which have been obtained show a good agreement with the experimental electrical characterizations results.
