The work presents the method to increase the electrical efficiency and power output of photovoltaic (PV) panel with the use of phase change material (PCM). CaCl₂.6H₂O–Fe₃Cl₂.6H₂O eutectic has a suitable melting point and high latent heat for temperature regulation of PV panel. The work has been focused on the experimental setup and simulation heat extraction from the PV panel with the use of ANSYS software. A modification of copper indium diselenide (CIS) PV module from Solar Frontier (SF170‐S) was made with a eutectic mixture (70:30) of calcium chloride hexahydrate (70%) and iron (III) chloride hexahydrate phase change material. The cell temperature of the PV panel with and without PCM was measured and compared for two typical days. The simulation of the PV‐PCM systems comprising both PV panels was performed using ANSYS (fluent) software, followed by the comparison of the results actual experimental data. The experimental results show that the maximum temperature difference on the surface of PV panel without PCM was 9°C higher than that on the panel with PCM in a period of 1 day. Referring to experimental results, the calculation of the maximum and average increase of power gain was made for PV‐PCM panel. Final results show that the electricity production of PV‐PCM panel was higher for 96.55 Whr in a particular day of experimentation.

无机相变材料提高铜铟二硒化物光伏组件的性能

这项工作提出了一种通过使用相变材料（PCM）来提高光伏（PV）面板的电效率和功率输出的方法。CaCl ₂ .6H ₂ O–Fe ₃ Cl ₂ .6H ₂共晶具有合适的熔点和高潜热，可用于调节光伏面板的温度。这项工作的重点是使用ANSYS软件从PV面板进行实验设置和模拟热量提取。用六水合氯化钙（70％）和六水合氯化铁（III）的共晶混合物（70:30）制成了Solar Frontier（SF170-S）的铜铟二硒化物（CIS）光伏组件。测量带有和不带有PCM的光伏面板的电池温度，并比较两天的典型时间。使用ANSYS（fluent）软件对包含两个PV面板的PV-PCM系统进行仿真，然后将结果与实际实验数据进行比较。实验结果表明，在1天的时间内，不带PCM的PV面板表面的最大温差比带PCM的面板高9°C。参考实验结果，对PV-PCM面板进行了功率增益的最大和平均增加的计算。最终结果表明，在特定的实验天中，PV-PCM面板的发电量为96.55 Whr。
