SOLAR CELL AND SOLAR MODULE

摘要

A solar module with improved output characteristics is provided. A finger portion (21a) includes a finger portion main body (21a1), a wide portion (21a2) which is wider than the finger portion main body (21a1) and is connected electrically to a wiring member (30), and a narrow portion (21a3) which is narrower than the finger portion main body (21a1). A finger portion (22a) includes a finger portion main body (22a1), a wide portion (22a2) which is wider than the finger portion main body (22a1) and is connected electrically to a wiring member (30), and a narrow portion (22a3) which is narrower than the finger portion main body (22a1). Wide portion (21a2) is arranged next to narrow portion (22a3) in the y-direction, and wide portion (22a2) is arranged next to narrow portion (21a3) in the y-direction.

主权项

1. A solar module comprising:
a solar cell having a first electrode and a second electrode on a main surface, and a wiring member electrically connected to the solar cell; the first electrode and the second electrode each having: a finger portion extending in the first direction and arranged alternatingly in another direction orthogonal to the first direction; the finger portion of the first electrode including: a first finger portion main body, a first wide portion being wider than the first finger portion main body and connected electrically to the wiring member, and a first narrow portion being narrower than the first finger portion main body; the finger portion of the second electrode including: a second finger portion main body, a second wide portion being wider than the second finger portion main body and connected electrically to the wiring member, and a second narrow portion being narrower than the second finger portion main body; the first wide portion is arranged next to the second narrow portion in the other direction, and the second wide portion is arranged next to the first narrow portion in the other direction.
