太陽電池素子および太陽電池モジュール
Document Type and Number:
Japanese Patent JP6525583
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a solar battery element that can be enhanced in output characteristic when a solar battery module is manufactured.SOLUTION: A solar battery element has a semiconductor substrate having a front principal surface and a back principal surface, and passivation portions which are provided to both of a first area located at a peripheral edge portion and a second area surrounded by the first area on the back principal surface of the semiconductor substrate. When the back principal surface of the semiconductor substrate is viewed in plan, the rate of the plane area occupied in the first area by the passivation portion to the plane area of the first areas is smaller than the rate of the plane area occupied in the second area by the passivation portion to the plane area of the second area.SELECTED DRAWING: Figure 3
