太阳电池在发电运行时大部分时间处于不同斜入射辐照条件,然而太阳电池及其组件的输出功率参数都是在垂直入射辐照下测量并成为衡量其发电能力的标准.对不同类型绒面的太阳电池,用这样的标准来衡量比较其实际发电运行输出可能会产生出入.通过对金字塔型绒面的单晶硅太阳电池与球窝型绒面的多晶硅太阳电池在斜入射光照时的光反射情况和两种类型组件的实际发电情况进行理论分析和实验测量,得到以下结论:按照现行标准测量结果标称输出性能,多晶硅太阳电池的实际运行发电能力相对于单晶硅太阳电池而言被略为低估了,但低估程度小于3%.一般而言,各种减反射手段所优化的实际是垂直入射辐照条件下的发电输出结果,其实际运行发电效果增益并不如标准测量结果所显示的那么大.

In real running, solar cells are mostly under obliquely incident light. However, the power output parameters of solar cells and modules are measured under vertically incident light, and they are used as a standard measure of the power output. This may cause problem in judging the real power output capability of differently surface-textured solar cells. Through theoretical analysis of light reflection and tests of the actual electrical current output of both the pyramid-type textured mono-crystalline and the pit-type textured multi-crystalline silicon solar cells and modules,it is shown that, the power output in real running of multi-crystalline solar cell relative to the mono-crystalline solar cell is slightly underestimated, if the current standard output parameters are used to judge the output performance. Further analysis indicates that the underestimation is less than 3%. Generally, various methods of antireflection actually optimize the power output under vertically incident lighting, while the gain of power output in real running would not as much as the standard measurement result exhibits.
