Theoretical Study of Hybrid Solar Cell Parameters Evaluation From I-V Characteristics

Abstract

Photovoltaics, which convert directly solar energy into electricity, provide a practical and sustainable solution to the challenge of meeting the increasing global energy demand. Computer simulation is an important tool for investigating solar cell device’s behavior and optimizing their performance. This work develops a new approach to retrieve the five parameters of the single diode equivalent solar cell/module model using the measured current-voltage data and its derivative (G=dI/dV). A nonlinear least-square technique based on the Newton-Raphson method under MATLAB Program is applied to determine the five parameters of the hybrid solar cell including under different temperature.
