Title:
SOLAR CELL AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/2011/129503
Kind Code:
A1
Abstract:
A method for manufacturing a solar cell includes forming a textured surface having a plurality of jagged portion at a surface of a substrate of a first conductive type; forming an emitter portion by doping an impurity into the substrate, the emitter portion having a second conductive type opposite to the first conductive type; removing a portion of the emitter portion by using a dry etching method, to form an emitter region; forming an anti-reflection layer on the emitter region; and forming a first electrode connected to the emitter region and a second electrode connected to the substrate.
