Part II: Enhanced Performance of Concentrating Photovoltaic-Thermal Air Collector with Fresnel Lens and Compound Parabolic Concentrator (CPC)

Abstract

In Part I of this study, the literature study on the types of methodologies applied by previous studies and the methodologies the suitable applied for this experimental study was provided. In this study (Part II), the methodologies are applied and the concentrating PVT air collector is fabricated based on the adopted methodologies. The heat is extracted by a working fluid (air), which can be collected and utilized for other domestic and industrial purposes. The highest thermal and electrical efficiencies of the cPVT collector in the present study were approximately 50 % and 12.9 % respectively; and achieved a total combined efficiency of approximately 80 % at average solar irradiation level of 750 W/m2, mass flow rate of 0.03 kg/s with the geometric concentration ratio of FL and CPC at 1.65 and 1.78 respectively.
