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.

预测用于 III-V 多结微聚光光伏的漫射集光器的年能量产量提高

采用双轴跟踪的传统聚光光伏 (CPV) 通常仅在具有大量直射阳光的位置与更便宜、效率更低的替代方案相比具有经济竞争力。以硅背板的形式将漫射光收集器添加到 CPV 面板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。但是，要了解分散收集的性能优势，需要一个现实的预测工具来预测不同位置的性能。我们引入了一个模型来评估混合 CPV 和 Si 模块的年发电量，并将结果与​​几种传统的独立 Si 和 CPV 模块进行比较。
