Analytical modelling and analysis of thermal behavior for series resistance of solar cell

Abstract

In this paper, the analysis of the nonlinear and complex modelling of a solar cell is addressed, to study its thermal behaviour. From literature it is well known that the output power of a solar cell monotonically decreases with the temperature; here, we investigate the specific expression based on derivation of current and power to simplify the equation model. Thus, applying the specific expression of the series resistance, we analyze the relation characteristics between the power and the temperature. Moreover, we aim to present a method to determine the specific theoretical expression of the series resistance with combination of parallel parasitic resistances. The analytical model equation is tested and compared with experimental results to add validity to the model
