摘　　要：针对太阳能电池高温工况下光电转换效率衰减问题,通过熔融法制备了一种由C_(16)H_(34)O-C_(16)H_(32)O_(2)与膨胀石墨复合而成的新型共晶相变储能材料,并基于此材料设计了太阳能电池装置。实验结果表明,该共晶相变储能材料的相变潜热较高,达到了182.3kJ/kg;相变温度适宜,为43.2℃,能有效缓冲温度波动。利用该材料制备的太阳能电池板实现22.5%的高光电转换效率,电压输出平均增益0.42V,功率产出平均增益3%。该太阳能电池板优于传统硅基电池板,且在抗老化和环境适应性方面表现卓越。上述结果说明将该材料应用于太阳能电池板热能控制,能有效提高太阳能电池板的电力生产效率和运行可靠性,为太阳能电池板的高效热管理提供新方案。To address the issue of photovoltaic conversion efficiency degradation in solar cells under high-temperature condition,a new eutectic phase change energy storage material composed of C_(16)H_(34)O-C_(16)H_(32)O_(2)and expanded graphite composite was developed.The eutectic phase change energy storage material was prepared by the melting method,and the solar cell device was designed using this material.The experimental results show that the latent heat of the eutectic phase change energy storage material reaches 182.3 kJ/kg,with an optimal phase transition temperature of 43.2℃,which can effectively mitigate the temperature fluctuations.The solar panel made with this material has an average voltage output increase of 0.42 V,an average power output improvement of 3%,and a high photoelectric conversion efficiency of 22.5%.This solar panel outperforms traditional silicon-based panels and demonstrates excellent aging resistance and environmental adaptability.These findings suggest that using this material for thermal management of solar panels can significantly increase the operational dependability and power production efficiency of the panels,offering a new approach to effective thermal management of the solar panels.
