Photovoltaic thermal hybrid solar collectors, also known as hybrid PV/T systems or PVT, is a system that converts solar radiation into thermal and electrical energy.
These systems combine a photovoltaic cell, which converts electromagnetic radiation (photons) into electricity, with a solar thermal collector, which captures the remaining energy and removes waste heat from the PV module. Photovoltaic (PV) cells suffer from a drop in efficiency with the rise in temperature due to increased resistance. Such systems can be engineered to carry heat away from the PV cells thereby cooling the cells and thus improving their efficiency by lowering resistance.
The result is a cool working PV panel with higher efficiency and longer life time due to the elimination of decay of Si and the production of hot water that can be used for residential, commercial or industrial applications.
