Napelem hőmérsékletfüggésének kísérleten és szimuláción alapuló vizsgálata

Abstract

This paper presents the temperature dependence of solar cell characteristics by laboratory measurements and numerical simulation in case of cooled and non-cooled solar cells. The voltage and current level of electricity, provided by solar cells are highly influenced by the temperature change. The output voltage level of both an idle and a loaded solar cell is decreased by the temperature increase which also leads to power decrease and efficiency deterioration. The intensity increase of the irradiating light linearly increase the current, provided by the power cell which highly increase the temperature of the solar cell and that leads to voltage decrease and efficiency deterioration too. To prevent these processes, it is needed to reduce the temperature of the solar cells. The measured characteristic curves at different temperatures are presented in this paper.
