摘要
理论研究了槽式反射聚光器上平面光伏电池表面可获得的能流密度的分布。研究发现,平面光伏电池板上能流密度的分布呈三个区域,由中心向两侧依次是能流密度为0 的区域、能流密度大于入射光区域和小于入射光的区域。对能流密度分布曲线拟合发现,平面光伏电池板上能流密度由中间向边缘呈指数函数减弱,且平面光伏电池板越接近抛物反射面的焦点,平面光伏电池板的半宽越小,平均能流密度越大,但衰减越快,能流密度的分布越不均匀。将计算结果与文献中的测量结果进行比较,证明了计算结果的正确性。
Abstract
The flux density distribution on the plane photovoltaic cells of parabolic trough concentrator is theoretically studied. The results show that the flux density on plane photovoltaic cells distributed in three regions, which from the center to both sides are flux density is zero, flux density is greater than incident light and flux density is smaller than incident light. The flux density distribution curve is fitted and flux density goes down exponentially from the center to the edge. The closer the photovoltaic cell stay to parabolic focal and higher flux density is obtained and more quickly the flux density goes down. The validity of the result is demonstrated by comparing result with that in references.
