Abstract
Official abstract text for this publication.
A solar cell according to an embodiment of the invention includes a substrate of a first conductive type, an emitter region of a second conductive type opposite the first conductive type, which is positioned at the substrate, an anti-reflection layer including a first opening exposing the emitter region and a plurality of second openings which expose the emitter region and are separated from one another, a first electrode which is positioned on a first portion of the emitter region exposed through the first opening and is connected to the first portion, a first bus bar which is positioned on a second portion of the emitter region exposed through the plurality of second openings and is connected to the second portion and the first electrode, and a second electrode which is positioned on the substrate and is connected to the substrate.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for manufacturing a solar cell comprising: doping impurities of a first conductive type or impurities of a second conductive type opposite the first conductive type on a first surface of a semiconductor substrate of the first conductive type to form an impurity region; forming a passivation layer on the impurity region; forming an impurity layer of the same conductive type as the impurity region on the passivation layer; selectively irradiatin…
