In the pursuit of mitigating greenhouse gas emissions, the adoption of clean energy production has emerged as an imperative strategy. Thin film CdTe photovoltaic (PV) modules have become widely popular in commercial applications owing to their remarkable attributes, such as superior absorption capabilities, direct band gap material, and single junction operational efficiency. CdTe PV modules have secured a prominent status within the photovoltaic technology landscape by demonstrating a favourable band gap optimisation, better temperature coefficient, and enhanced energy yield.
This research presents an exploration of PV resistance modelling via a numerical methodology. A comprehensive CdTe PV module model is developed in the Matlab Simulink environment. Furthermore, the study explores the detailed performance of a 110 W thin film CdTe PV module. Critical parameters such as open circuit voltage, short circuit current, and maximum power are subjected to meticulous validation against data from established commercial photovoltaic modules. The efficiency and fill factor of the CdTe PV module are judiciously analysed with the changing weather condition.
Impressively, the analysis highlights the model’s exceptional precision under the considered conditions, particularly in the context of maximum power, where the relative error remains under 0.1%. Remarkably aligning with reference module parameters, the characteristic PV parameters exhibit remarkable closeness, with an overall relative error of less than 1.63% for all PV parameters under standard test conditions.
Moreover, a statistical measure named coefficient of determination ‘R2’ is found very near to 1 for all characteristics described and it satisfies the actual nature of the characteristics curve.
