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

摘要

A plate-shaped silicon (11, 31) having a through hole (13A) and a cut-out portion (31B) without executing processings such as laser machining and machining is provided low cost so as to increase the demand for solar cells. Using the produced plate-shaped silicon (11, 31), a high-designability transparent (see-through) solar cell, a solar cell module, and an emitter wrap through solar cell are provided at low cost. A method for manufacturing a plate-shaped silicon by bringing a substrate into contact with a silicon melt and growing a crystal of plate-shaped silicon on the substrate is characterized by comprising a step of forming a through hole (13A) and/or a cut-out portion (31B) in the plate-shaped silicon (11, 31) while growing a crystal of a plate-shaped silicon on the substrate.
