Method for producing plate silicon, substrate for producing plate silicon, plate silicon, solar cell using the plate silicon, and solar cell module

摘要

In order to increase the demand for solar cells, the present invention reduces the plate-like silicon (11, 31) having through holes (13A) and notches (31B) without going through a process such as laser processing or machining. The purpose is to provide at a cost. Further, by using the obtained plate-like silicon (11, 31), a highly transmissive (see-through) solar cell, solar cell module, emitter-wrap-through solar cell, or solar cell module having a high design property It is intended to provide at a low price. For this reason, the plate-like silicon manufacturing method of the present invention is a plate-like silicon manufacturing method in which a substrate is brought into contact with a silicon melt and silicon is crystal-grown on the substrate surface. ) Is grown, and a through hole (13A) and / or a notch (31B) is formed in the plate-like silicon (11, 31).
