Abstract
Official abstract text for this publication.
Provided are a paste for contacts and a solar cell using the same. The paste for contacts includes Al powder, glass frit, inorganic binder, and P-type oxidation containing I group elements.
First claim
Opening claim text (preview).
The invention claimed is: 1. A solar cell comprising: a front contact disposed on one surface of a semiconductor substrate; an anti-reflective layer on the semiconductor substrate; a back surface field (BSF) layer disposed on the other surface of the semiconductor substrate; and a rear contact disposed on the BSF layer; wherein the semiconductor substrate comprises: a silicon substrate; and an N + layer on the silicon substrate, wherein the N + layer is in physical contact with the anti-reflective layer, wherein the silicon substrate is in physical contact with the BSF layer, wherein the front contact is spaced apart from the semiconductor substrate, wherein the BSF layer has a thickness of 4.78 μm to 5.2 μm, wherein the BSF layer or the rear contact comprises a P-type oxidation, and wherein the P-type oxidation is expressed as the following Chemical Formula 2: Sr 1−X Na X Cu Y O Z [Chemical Formula 2] where, 0.03<X≦0.2, 1.5<Y≦2.5, 1.5<Z≦2.5. 2. The solar cell according to claim 1 , wherein each of the BSF layer and the rear contact comprises the P-type oxidation.
