Title:
SILICON WAFER FOR SOLAR CELLS AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2011/024910
Kind Code:
A1
Abstract:
Disclosed is a silicon wafer for solar cells that has a plurality of similarly-oriented, minute, linear depressions that are saw marks formed upon the front and back surfaces of the wafer, whereby the light receiving area of the wafer is expanded and high photoelectric conversion efficiency can be obtained. Furthermore, projection/depression formation processes other than slicing are simplified, and the production cost for silicon solar cells is reduced.
