SOLAR CELL AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: A solar cell and a method for manufacturing the same are provided to improve the productivity of the solar cell by reducing the recombination rate of electric charges in the vicinity of the surface of an emitter part. CONSTITUTION: A substrate(110) contains a first dopant in a first conductive type. The Substrate is textured to obtain a texturing surface with a plurality of protrusions(115). An emitter part(120) contains a second dopant in a second conductive type. The second conductive type is opposite to the first conductive type. The density of an anti reflection film(130) is varied according to location. A plurality of first electrodes is in electrical connection with the emitter part. A second electrode is in electrical connection with the substrate.
