摘　　要：针对目前高校太阳能电池实验教学大多基于单晶、多晶、非晶硅样品及不能解释不同电池性能差异本质原因的不足,新开设砷化镓单晶和硅单晶太阳能电池对比实验。该实验在暗伏安特性、开路电压和短路电流、输出特性等传统测量及数学拟合基础上,还给出在全光强范围内的最大输出功率值、开路电压短路电流的乘积值及其线性拟合,并据此提供全光强范围的填充因子曲线。最后,结合第一性原理方法计算的能带图,解释了两种太阳能电池性能差异的根本原因,弥补了以往实验教学的不足。As most experimental teaching of solar cells in colleges and universities is based on single crystal,polycrystalline and amorphous silicon samples and cannot explain the essential reasons for the differences in the performance of different batteries,a new comparative experiment of the gallium arsenide and silicon single crystal solar cells is set up.Based on the traditional measurement and mathematical fitting of dark volt ampere characteristics,open circuit voltage,short circuit current and output characteristics,the maximum output power value,the product value of open circuit voltage and short circuit current and their linear fitting in the full light intensity range are presented in this experiment,and the filling factor curve in the full light intensity range is provided.Finally,the energy band diagram calculated by the first principle method is used to explain the basic reason of the performance difference between the two kinds of solar cells,which makes up for the deficiency of the previous experimental teaching.
