Embodiment Construction

[0053]The advantages and features of the present invention, and the way of attaining them, will become apparent with reference to embodiments described below in conjunction with the accompanying drawings.

[0054]FIGS. 1 to 9 are sectional views sequentially illustrating a fabricating method of a solar cell in accordance with embodiments of the present invention.

[0055]FIGS. 1 to 8 are sectional views schematically illustrating a fabricating process of a completed solar cell shown in FIG. 9. Embodiments of the solar cell are not limited thereto, but may be fabricated through various processes which do not deviate from the technical scope of embodiments of the present invention.

[0056]First, as shown in FIG. 1, a substrate 100 (also referred to as a p-type semiconductor substrate 100) is prepared by doping a semiconductor substrate with a p-type semiconductor impurity. Examples of the semiconductor for the p-type semiconductor substrate 100 may be silicon.

[0057]In FIG. 1, texturing of the...

Abstract

Discussed herein are a solar cell and a fabricating method thereof. The solar cell includes a first conductivity-type semiconductor substrate, a second conductivity-type semiconductor layer formed on a front surface of the first conductivity-type semiconductor substrate, and having a conductivity opposite to that of the first conductivity-type semiconductor substrate, an anti-reflection film including at least one opening exposing a part of a surface of the second conductivity-type semiconductor layer, and formed on the second conductivity-type semiconductor layer, at least one front electrode contacting a part of the surface of the second conductivity-type semiconductor layer exposed through the at least one opening, and at least one rear electrode formed on a rear surface of the first conductivity-type semiconductor substrate, wherein the at least one front electrode includes a metal containing silver and lead-free glass frit.

Description

[0001]This application claims priority to and the benefit of Korean Patent Application No. 10-2009-0079934, filed on Aug. 27, 2009 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]Embodiments of the present invention relate to a solar cell and a fabricating method thereof, and more particularly to a fabricating method of a solar cell for producing the solar cell having a reliable quality and a high efficiency with a high yield, and reduce process costs while preventing or reducing environmental pollution.[0004]2. Discussion of the Related Art[0005]Recently, as exhaustion of existing energy resources, such as oil and coal, is expected, there is increasing interest in alternative energy sources. Among them, solar cells are a source of abundant energy and do not cause environmental pollution, and thus, are attracting wide attention. Types of solar cells include a solar...
