Effect of Temperature on Performance Parameters of Metallurgical Grade Polysilicon Solar Cells

Abstract

By the stable operation of the experiments in actual outdoor conditions nearly a year, we find that the property of metallurgical silicon solar cells proves to be stable. The results show that the relationship between S-P could be expressed as a quartic equation. As the higher surface temperature of solar cells at noon on sunny day, both the open circuit voltage and the operating voltage are lower, the output power is reduced. It is concluded that the water cooling on the surface of the solar cells when the temperature T>50°C could improve power generation efficiency.

Impact of Solar Radiation and Temperature Levels on the Variation of the Series and Shunt Resistors in Photovoltaic Modules

“…0 1 (19) and by combining the equations ( 17) and (18), the net equation for FF becomes; Temperature is a paramount factor that alters the band gap of semiconductor devices. Most of the semiconductor parameters are prone to changes with temperature [7]. In fact, temperature and the energy of electrons are deeply correlated.…”

“…[4]. This generated heat in addition to the possible increase in the ambient temperature affects the material properties of a PV cell which leads to negatively alter the power output of the PV cell, and consequently its efficiency [5,6,7]. To minimize the problem of raising temperature in PV modules, a cooling method of the module's surface is proposed to extract the heat and hence alleviate the heat problem.…”
