Introduction
Photovoltaic solar thermal (PVT) systems purpose is to produce both heat and electricity in a smaller area than if you were to have both a photovoltaic panel and a solar thermal system. The current design for PVT is to have a solar panel glued to a solar thermal system. PVTs purpose is to use the solar thermal system to cool the photovoltaic cells to perform better, as solar cells degrade with temperatures greater than 25 C. This means however, that the thermal aspect of the PVT has a significantly lower efficiency compared to just a solar thermal system (max 50% eff compared to 70+% eff).
