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.
