Investigating the Effect of Temperature on the Performance of Photovoltaic Cell

Abstract

One of the most important things to consider when choosing the type of solar cells when purchasing is efficiency, which is the most important thing that distinguishes a solar cell from another. The efficiency of the solar cell is influenced by weather factors such as wind speed, dust, relative humidity, and heat; the aim of this paper is to study the effect of solar cell temperature on its performance, using one-diode equivalent circuit model. This paper analyzed the relation between solar cell operating temperature with the slope of I-V characteristics curve, slope of P-V characteristics curve at each point as well as the PV module efficiency. Temperature changes have an impact on the slope of I-V and P-V characteristic curves, and an increase of 0.086 percent in temperature reduces the PV module's efficiency.
