Optical and electrical performance analysis of non-imaging low concentrating photovoltaic-thermal cogeneration system
A concentrating solar photovoltaic thermal(CPVT)cogeneration system is a dual output(electrical and thermal energy)system which consists of a concentrator,a PV module and a heat recovery system.In the case of conventional non-tracking compound parabolic concentrator(CPC)based CPVT system,non-uniform illumination and non-uniform temperature distribution on the PVT module reduces its electrical and thermal power output.In this work,a homogeniser is optimised and integrated to the truncated 3X CPC to reduce the illumination non-uniformity at all angles(from normal incidence to the acceptance angle).Further,a scaled down CPVT system is fabricated and optical and electrical analysis has been performed under solar simulator.The experimental results show promising improvement in electrical efficiency(>50%at high incidence angles)with the incorporation of homogeniser.The study proves that for CPC-PVT systems homogenisation is necessary for realizing better electrical and thermal performance.
