| 摘 要： | 基于槽式聚光太阳能系统分别对单晶硅电池阵列、多晶硅电池阵列、空间太阳电池阵列和砷化镓电池阵列进行测试实验. 结果表明，聚光后，前3种电池阵列的I-V曲线都趋于直线，输出功率急剧减少，系统效率下降较快. 而砷化镓电池阵列有较好的I-V曲线，其效率由聚光前的23.66%增加到26.50%，理论聚光比为16.92时，输出功率放大11.2倍，聚光光伏系统中可采用砷化镓电池阵列以提高效率. 砷化镓电池阵列Pm、FF和η的温度系数分别为-0.12W/K、-0.10%/K和-0.21%/K，为避免温度的影响须采用强制冷却方式保证电池效率，同时对外供热. 研究表明，10片单晶硅电池串联阵列最佳工作时的理论聚光比为4.23; 16片空间太阳电池串联阵列最佳工作时的理论聚光比为8.46. 研究工作对提高槽式聚光系统效率和大规模利用聚光光伏发电提供了依据.

| Abstract: | A series experiment works have been done with single crystalline silicon solar cell array,polysilicon solar cell array,super cell array and GaAs cell array through the trough concentrating solar system.The experimental results show that the I-V curve of the crystalline silicon,polysilicon and super cell arrays are beeline in the concentrating solar irradiance,which reduce the efficiency and decrease the output power.However the I-V curve of GaAs cell array is very good in the concentrating solar irradiance,... |
