Mathematic description

The theoretical effort invested in modeling the CPV receiver with solar cells immersed in liquid has not seen the intensive research and development activity. The studies of thermal model of solar cells have been mostly concentrated on photovoltaic system and hybrid photovoltaic thermal system. Radziemska [9] summarizes the recent progress obtained in the field of […]

Bozzoli1 1 Renewable Energies & Environmental Technologies research unit (REET), Fondazione Bruno Kessler (FBK),Via alla Cascata 56/C, I-38050 Povo (Tn), Italy* Corresponding Author, :rema@,fbk. eu Abstract In this work, we propose a solution to convection and conduction heat losses on an solar thermal collector. We have based our work starting […]

Energy balance model

The energy balance is considered for each component of the CPV receiver: Tc, Tvb and the fluid, Tf and Tfo. Some geometrical characteristics of the CPV receiver and the silicone oil properties are given in Table 1. 3.1. Solar energy model The irradiance absorbed by the vessel top, solar cells and vessel bottom are given […]
