在实际工作条件下，太阳能电池的温度升高，太阳能电池的转换效率随着温度的升高而降低。本研究采用喷涂的方法在光伏组件背面涂覆热辐射层，并对效果进行评价。涂层厚度为30 μm。有热辐射涂层的PV组件的温度低于没有热辐射涂层的PV组件的温度。采用热辐射涂层的光伏组件工作温度范围降低了2~3℃。由于有热辐射涂层，有热辐射涂层的光伏组件的开路电压比没有涂层的光伏组件的开路电压高0.1 V。
The temperature of solar cells increases under the actual operating conditions, and the conversion efficiency of solar cells decreases with increasing temperature. In this study, a thermal radiation layer was coated on the back sheet of the PV module by a spray coating method and the effect was evaluated. The thickness of the layer was 30 μm. The temperature of the PV module with the thermal radiation coating was lower than that of the PV module without the thermal radiation coating. And the operating temperature range of the PV module with the thermal radiation coating was decreased by 2~3°C. The open-circuit voltage of the PV module with the thermal radiation coating was 0.1 V higher than that of the module without the coating due to the thermal radiation coating.
