摘　　要：太阳能光伏电池在激光辐照条件下易出现热量累积问题,当前研究主要集中于单脉冲激光对其特性的影响,鲜少研究复合脉冲激光对其特性的影响,为此研究复合激光辐照对太阳能光伏电池特性的影响。依照傅里叶热传导原理构建热传导模型,并以等效电路表示太阳能光伏电池的光电转换模型,利用COMSOL与Matlab软件研究复合激光辐照对太阳能光伏电池温度变化与温度场分布的影响,以及能量密度差异条件下光电转换效率变化情况。实验结果显示:复合激光辐照条件下,太阳能光伏电池熔化损伤集中产生于纳秒激光辐照过程中,温度场在径向上表现出显著的高斯分布特征;复合激光辐照可提升太阳能光伏电池输出电功率。Solar photovoltaic cells are prone to heat accumulation under laser irradiation.The current research mainly focuses on the influence of single pulse laser on its characteristics,and there is little research on the influence of composite pulse laser on its characteristics.Therefore,this paper studies the influence of laser irradiation on the characteristics of solar photovoltaic cells.The heat conduction model is constructed according to the Fourier heat conduction principle,and the photoelectric conversion model of solar photovoltaic cells is represented by equivalent circuit.The influence of compound laser irradiation on the temperature change and temperature field distribution of solar photovoltaic cells and the change of photoelectric conversion efficiency under the condition of energy density difference are studied by COMSOL and MATLAB software.The results show that under the condition of compound laser irradiation,the melting damage of solar photovoltaic cells mainly occurs in the process of nanosecond laser irradiation,and the temperature field shows significant Gaussian distribution in the radial direction;Compound laser irradiation can improve the output power of solar photovoltaic cells.
