Method for eliminating light energy loss of invalid region of photovoltaic module and photovoltaic module

The invention discloses a method for eliminating light energy loss of an invalid region of a photovoltaic module and the photovoltaic module. Compound paraboloids are arranged on a glass panel of thephotovoltaic module at the position corresponding to a main grid line on a cell and at the positions corresponding to cell array splicing gaps and invalid edges to reflect the light passing through the compound paraboloids to an effective area of each cell so as to eliminate light energy loss at the positions of the main grid lines of the cells, the splicing gaps and the invalid edges. Through thecompound paraboloids at the positions of the main grid lines of the cells, the light energy loss of the area can be reduced; and by properly increasing the widths of the main grid lines or adjustingthe number of the main grid lines, the electric energy loss caused by welding strips in the photovoltaic module can be reduced. 本发明公开了一种消除光伏组件无效区域光能损失的方法及光伏组件，在光伏组件的玻璃面板上与电池片上的主栅线对应的位置以及电池片阵列拼接间隙和无效边缘对应的位置处，设置复合抛物面将经过复合抛物面的光线反射
