Abstract Concentrating Photovoltaic technology is a promising option in power generation using the photovoltaics compared to the conventional flat PV system. This study investigates the performance of a high concentrated photovoltaic single solar cell module attached to a multi-layered microchannel heat sink. The system has been tested the first time experimentally both at indoor and outdoor conditions. The indoor characterization of the system investigated the effect of varying the number of the layers of the heat sink and the flow rate of the fluid electrically and thermally. The experiments show that varying the number of the heat sink layers from 1-layer to 3-layers increase the maximum electrical generation by 10% and reduces the cell temperature by 3.15 °C under the same fluid flow rate of 30 ml/min. The outdoor experiments show the maximum output electrical generation of the system of 4.60 W and the short circuit current of 1.96 A. The maximum solar cell temperature was maintained below 61 °C where the extracted heat of the system was 12.85 W which represents of 74.9% of the total generated power.

附着在多层微通道散热器上的聚光光伏的室内外表征

摘要 与传统的平面光伏系统相比，聚光光伏技术是利用光伏发电的一种有前景的选择。本研究调查了连接到多层微通道散热器的高聚光光伏单太阳能电池模块的性能。该系统已首次在室内和室外条件下进行了实验测试。该系统的室内特性研究了改变散热器层数和流体在电和热方面的流速的影响。实验表明，在相同的流体流速为 30 ml/min 的情况下，将散热器层的数量从 1 层改为 3 层可将最大发电量提高 10%，并使电池温度降低 3.15°C。
