 Effects of partial shading on thermal stress and exergetic efficiency for a high concentrator photovoltaicWilliam J. Cameron, Mussad M. Alzahrani, James Yule, Katie Shanks, K.S. Reddy and Tapas K. Mallick Energy, 2024, vol. 288, issue C Abstract: Highly concentrated photovoltaic systems can produce higher energy yields than conventional photovoltaic panels but have yet to reach widespread deployment, partly because of lower lifetime and hence cost effectiveness. One limiting factor in the lifetime is the excessive generation of thermal stress. This study takes a multi-objective approach to the calibration of a highly concentrated photovoltaic thermal hybrid system. Novelty is found by exploring the relationship and trade-off between thermal stress and exergetic efficiency. A variety of optical configurations are compared by partially shading the input aperture of the primary optics. Similarly, adjustments to the receiver are made by changing the angle of the solar cell by 45°. To minimise light spillage. The primary and secondary optic positions stay the same throughout all calibrations.
