The Future of Solar Energy | MIT Energy Initiative

The Future of Solar Energy considers only the two widely recognized classes of technologies for converting solar energy into electricity — photovoltaics (PV) and concentrated solar power (CSP), sometimes called solar thermal) — in their current and plausible future forms. Because energy supply facilities typically last several decades, technologies in these classes will dominate solar

How Does Heat Affect Solar Panel Efficiencies?

To further the explanation, solar panels work by having the photons from the sunlight knock electrons loose from their atoms. When the solar panel gets hotter, the number of electrons in an excited state increases. This results of having the silicon solar cell generating more current but less voltage and therefore lowers its efficiency. Thanks
