边框阴影对BIPVT系统光电光热综合性能的影响
摘要：摘要太阳能光电/光热建筑一体化（BIPV/T）综合利用系统中的空气隔热层可以提高系统光热效率，但支撑边框会在板芯上形成阴影，该阴影会影响BIPV/T的综合性能。本文建立了二维的辐照场模型、传热模型和电学模型，探索边框阴影分布规律及其对BIPV/T光电光热性能的影响。研究结果表明：以北京地区为例，系统的边框阴影显著且全年呈规律性分布；全年来看，边框阴影对系统的光热性能影响较小，日平均光热效率增/损的最大值为0.49%；阴影对系统的光电性能影响显著，日平均光电效率损失的最大值为13.19%；由阴影引起的月平均发电量损失介于0.1% ~ 13.2%之间。

Abstract:：The air insulation layer in the building integrated photovoltaic/thermal (BIPV/T) system can improve the photothermal efficiency. But the support frame will form a shadow on the board core, and the shadow will affect the overall performance of BIPV/T. In this paper, two-dimensional radiation field model, heat transfer model and electrical model are established. The shadow distribution and the effect on the photovoltaic/thermal performance of BIPV/T are explored. Results indicate: taking the Beijing area as an example, the border shadow of the system are obvious and distributed regularly throughout the year. For the whole year, the shadow has little effect on the photothermal performance of the system, and the maximum daily increase/loss of photothermal efficiency is 0.49%. The effect of shadow on the photovoltaic performance of the system is significant, and the maximum loss of the average photovoltaic efficiency is 13.19%. The monthly average power loss due to shadows ranged from 0.1% to 13.2%.
