SUBSTRATE FOR SOLAR CELL, AND SOLAR CELL

WIPO Patent Application WO/2012/026357

A1

Provided is a substrate for a solar cell, wherein a flat chamfered portion is formed on one corner of a silicon substrate having a square shape in a planar view, or a notch is formed on the corner or close to the corner. This invention makes it possible to easily check the position of the substrate and determine the direction of the substrate in a solar cell manufacturing step, and suppresses failures generated due to the direction of the substrate.
