Abstract

Disclosed is a solar cell string that suppresses reductions in the packaging density of solar cells and that enables the prevention of damage to solar cells while reducing production time. The solar cell string (1) is equipped with a plurality of solar cells (2) and a circuit board (3). The semiconductor substrate (10) of each solar cell includes an n-type conductive region (10c), and an n+-type conductive region (10d) and p-type conductive regions (10e and 10f) that are disposed on the rear side (10b) of the semiconductor substrate. The circuit board electrically connects the n+-type conductive region of the solar cell (2a) and the p-type conductive region (10e) of the solar cell (2b), and electrically connects the p-type conductive region (10f) of the solar cell (2a) and the n+-type conductive region (10d) of the solar cell (2b).

Description

technical field [0001] The invention relates to a solar battery string, a solar battery module and a solar battery unit. Background technique [0002] Due to increasing concern for global environmental issues, solar cells that convert light energy into electrical energy are attracting attention as clean energy with little environmental load. [0003] As materials for solar cells, there are various kinds of materials such as compound semiconductor materials and organic materials, but silicon crystals are currently the mainstream. [0004] Generally, a solar battery is rarely used as a single solar battery unit, but a plurality of solar battery units are connected in series or in parallel to form a solar battery string to obtain a predetermined output. The solar cell string is sealed with a sealing material and used as a solar cell module. [0005] However, during the use of the solar cell module, if a shadow is generated on some solar cells due to some reasons, the voltage ...
