Slicing method of regular polygon solar cell
A technology of solar cells and solar cells, which is applied in the field of solar cells, can solve problems such as obstacles to the development of regular polygonal cells, a reduction in the proportion of effective area, and the inability to directly splice into rectangular components, so as to reduce material costs, reduce electrical losses, and utilize rate-enhancing effect
