METHOD FOR FABRICATING A SOLAR CELL, CAPABLE OF IMPROVING LIGHT ABSORPTION RATE BY GUIDING INCIDENT LIGHT TO BE DIFFUSED

摘要

PURPOSE: A method for fabricating a solar cell is provided to minimize damage to the textured surface by performing a thermal process the textured surface. ;CONSTITUTION: In a method for fabricating a solar cell, a crystalline silicon substrate(201) is prepared. A surface texturing process of a substrate is performed. The surface of the silicon substrate is process to be uneven through the texturing process A mechanical stability is applied to a concavo-convex(202) to reinforce the surface through a thermal process which is performed under 700~800°C.;COPYRIGHT KIPO 2011
