Abstract
ABSTRACT The degradation effect of triple-junction solar cells due to exposure in practical conditions and its influence on the performance of Fresnel concentrated photovoltaic system has been studied. To analyse the behavioural performance theoretically and experimentally, four secondary concentrators of similar physical structure but with reflective and refractive properties such as a refractive prism, reflective prism, refractive, and reflective compound parabolic concentrator are considered. Observations characterising solar cells as new, semi-old, and old based on their degradation reveal an efficiency decrease of up to 42%. Also, results demonstrate better performance for reflective profiles, particularly with 17% overall efficiency by reflective prism, besides Fresnel lens without any secondary concentrator exhibits the highest efficiency of 21%. The behavioural characteristics of the individual system have been addressed based on practical errors.
期刊介绍：
Engineering and sustainable development are intrinsically linked. All capital plant and every consumable product depends on an engineering input through design, manufacture and operation, if not for the product itself then for the equipment required to process and transport the raw materials and the final product. Many aspects of sustainable development depend directly on appropriate and timely actions by engineers. Engineering is an extended process of analysis, synthesis, evaluation and execution and, therefore, it is argued that engineers must be involved from the outset of any proposal to develop sustainable solutions. Engineering embraces many disciplines and truly sustainable solutions are usually inter-disciplinary in nature.
