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.

四种菲涅耳聚光光伏系统多结太阳能电池室外退化评价

摘要研究了三结太阳能电池在实际条件下暴露的降解效应及其对菲涅耳聚光光伏系统性能的影响。为了从理论上和实验上分析四种物理结构相似但具有反射和折射特性的二次聚光器，即折射棱镜、反射棱镜、折射和反射复合抛物面聚光器的性能。根据太阳能电池的退化情况，将其分为新电池、半旧电池和旧电池，结果显示效率下降幅度高达42%。另外，采用反射棱镜的反射型透镜的总效率达到17%，而不采用二次聚光器的菲涅耳透镜的总效率最高，达到21%。个别系统的行为特征已根据实际误差加以处理。

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.
