Abstract

Abstract. Conventional concentrator photovoltaics (CPV) employing two-axis tracking are generally only economically competitive with cheaper, less efficient alternatives in locations with large amounts of direct sunlight. Adding a diffuse light collector to a CPV panel in the form of a silicon back panel can potentially improve the light collection under cloudy conditions and expand the range of climates in which CPV is useful. However, to understand the performance advantages available with diffuse collection, a realistic forecasting tool to predict performance in different locations is required. We introduce a model to evaluate the annual energy yield of a hybrid CPV and Si module and compare the results with several conventional stand-alone Si and CPV modules. The advantages of including a bifacial Si panel as the diffuse collector will also be investigated.
预测III-V多结微聚光灯光伏散射光收集器的年能量产量提高
摘要采用双轴跟踪的传统集中器光伏(CPV)通常只有在阳光直射量大的地方与更便宜、效率更低的替代品具有经济竞争力。以硅背板的形式在CPV面板上添加漫射集光器可以潜在地改善多云条件下的光收集,并扩大CPV有用的气候范围。然而,为了了解扩散收集的性能优势,需要一个现实的预测工具来预测不同位置的性能。我们介绍了一个评估CPV和硅混合模块年发电量的模型,并将其结果与几种传统的独立硅和CPV模块进行了比较。还将研究包括双面硅面板作为扩散收集器的优点。
