Energetic simulation of a dielectric photovoltaic-thermal concentrator

A solar concentrating photovoltaic-thermal (CPVT) module with cell immersion in dielectric liquid has been modelled and energetically simulated. The concentrator focuses radiation linearly by using a cylindrical shape optics made of polymethyl methacrylate. The geometric concentration is 12 suns wit...
