Design and analysis of a novel concentrated photovoltaic–thermal receiver concept

摘要: Solar concentrators, which focus the sunlight on a small surface of solar cells, are promising way reducing expensive semiconductor area and thus also energy generation costs photovoltaics. This paper presents design analysis concentrated photovoltaic (CPV) receiver for linear Fresnel concentrator mirror module. The is designed as hybrid photovoltaic–thermal (CPV-T) receiver, enables simultaneous power heat in one compact receiver. Spectral splitting with selective absorptive media thermal decoupling carrier cells improves electrical efficiency. Computational fluid dynamics (CFD) simulations various receiver-setups result an efficiency up to 6.2% 61.2% at specific selected operating point. 62% wavelengths incoming spectrum between 500 1100 nm hit cells.
