SOLAR CELL AND METHOD FOR MANUFACTURING THE SAME
First Claim
1. A method for manufacturing a solar cell comprising:
- forming an emitter layer of a second conductive type opposite a first conductive type on a substrate of the first conductive type;
sequentially positioning the substrate in a plurality of chambers to form an anti-reflection layer on the emitter layer and to form a passivation layer including at least one exposed portion on a rear surface of the substrate opposite an incident surface of the substrate;
coating a first paste on the anti-reflection layer to form a first electrode pattern;
coating a second paste on the passivation layer and on a portion of the substrate exposed by the exposed portion to form a second electrode conductive layer pattern; and
performing a thermal process on the substrate having the first electrode pattern and the second electrode conductive layer pattern to form a plurality of first electrodes electrically connected to the emitter layer and to form a second electrode conductive layer including at least one second electrode electrically connected to the substrate.

Abstract
The present invention relates to a solar cell. The solar cell includes a substrate of a first conductive type, an emitter layer of a second conductive type opposite the first conductive type on the substrate, first and second anti-reflection layers that are sequentially positioned on the emitter layer, a first electrode electrically connected to the emitter layer, first to third passivation layers that are sequentially positioned on the substrate, each of the first to third passivation layers including a plurality of exposed portions, and a plurality of second electrodes electrically connected to portions of the substrate exposed by the plurality of exposed portions.
