I found in an article that high temeratures have negative impact over photovoltaic cells but i haven't found the answer. I fail to understand it, because of what i know on a higher temperature electrons have higher energies and so I think it increases photovoltaic cells efficiency . If the assertion in the article is true then the yield is higher in winter than in summer which is a good thing i guess. Is that true? If so, why?
