Abstract

Official abstract text for this publication.

A solar cell includes a solar cell substrate including a principal surface on which a p-type surface and an n-type surface are exposed, a p-side electrode formed on the p-type surface and including a first linear portion linearly extending in a first direction, and an n-side electrode formed on the n-type surface and including a second linear portion linearly extending in the first direction and arranged next to the first linear portion in a second direction orthogonal to the first direction. Corners of a tip end of at least one of the first and second linear portions are formed in a chamfered shape.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of manufacturing a solar cell including: a solar cell substrate including a p-type surface and an n-type surface formed on a principal surface side of the solar cell substrate; a p-side electrode formed on the p-type surface and including a first linear portion linearly extending in a first direction; and an n-side electrode formed on the n-type surface and including a second linear portion linearly extending in the first direction and arranged next to the first linear portion in a second direction orthogonal to the first direction, corners of a tip end of at least one of the first and second linear portions being formed in a round shape, the method comprising: forming a p-type surface and an n-type surface on a principal surface of a solar cell substrate such that the p-type surface and the n-type surface extends in a linear shape in a first direction and corners of tip ends of the p-type and n-type surfaces are formed in a round shape; forming a seed layer on the a p-type or n-type surface such that corners of a tip end of the seed layer are formed in a round shape; and forming a plating on the seed layer, thereby forming a p-side and n-side electrode. 2. A method of manufacturing a solar cell comprises: forming a seed layer on a p-type or n-type surface of a solar cell substrate such that corners of a tip end of the seed layer are formed in a round shape; and forming an electroplated coating on the seed layer, thereby forming an electrode on the-type or n-type surface whose tip end has corners formed in a round shape. 3. The method of manufacturing a solar cell according to claim 2 , wherein the electroplated coating is formed by electroplating. 4. The method of manufacturing a solar cell according to claim 3 , further comprises: forming a p-type amorphous semiconductor layer and an n-type amorphous semiconductor layer on a principal surface side of the solar cell substrate, wherein the seed layer is formed on the p-type amorphous semiconductor layer and the n-type amorphous semiconductor layer. 5. The method of manufacturing a solar cell according to claim 4 , further comprises: forming an i-type amorphous semiconductor layer on a principal surface side of the solar cell substrate, wherein at least one of the p-type amorphous semiconductor layer and the n-type amorphous semiconductor layer is formed on the i-type amorphous semiconductor layer.
