Lee, Pei Shan (2021) Optical Analysis Of Crossed Compound Parabolic Concentrator For High Concentrator Photovoltaic System. Master dissertation/thesis, UTAR.
Abstract
A comprehensive optical analysis on assembly of dielectric compound parabolic concentrator (CCPC)filled 3D crossed and concentrator photovoltaic (CPV) module is presented by embracing the consideration of spectral irradiance, incident angles and breakdown optical losses. The theoretical modelling supported by experiments has been carried out to evaluate the optical ef ficiency of the CCPCCPV assembly module by investigating detailed optical losses at each layer of the components. From our breakdown optical analysis, total Fresnel reflection loss of 11.27%, absorption loss within CCPC lens of 11.59% and other losses of 4.79% are obtained to reach the optical efficiency of 77.3% of equivalent solar concentration ratio (SCR) of 4.65 out of geometrical concentration ratio (GCR) of 5.998 suns. Furthermore, indoor and outdoor measurements have proven the actual SCR of 4.57 an d 4.48 respectively, which are also equivalent to optical efficiencies of 76.2% and 74.4% accordingly. The experimental results have strongly verified the simulated result of optical analysis on CCPC comprehensive theoretical modelCPV assembly module. The ling of secondary optics is essential for the performance optimization of CPV system in the future.
