A British-Chinese research group has created a new framework to assess the performance and efficiency limits of photovoltaic-thermal solar panels. They say that the improvement of spectral-splitting (SS) filters in the devices will be the key to their future commercial success.Photovoltaic-thermal (PVT) solar panels have barely been developed thus far, compared to PV modules and solar-thermal panels. This is mainly due to their lower overall efficiency and longer payback times, as well as a number of technical challenges. Although a considerable number of PVT products are currently available for ...Den vollständigen Artikel lesen ...
