COLLECTOR SHEET FOR SOLAR CELL, AND SOLAR CELL MODULE USING COLLECTOR SHEET FOR SOLAR CELL

摘要

Provided is a collector sheet for a solar cell, and contributing to improvement of power generation efficiency. A collector sheet (5) for a solar cell is disposed on the rear surface side of a solar cell element (4), and is provided with: a circuit (54), which is formed on the front surface of a resin base material (53), and which is configured of a wiring section (541) composed of a metal, and a non-wiring section (542); and an insulating layer (52), which is formed on the circuit (54). Light extraction to the solar cell element (4) due to reflection from the insulating layer (52) is increased, said insulating layer being disposed at the element periphery of the solar cell element (4), by having a white pigment contained in the insulating layer (52), and power generation efficiency is improved even in a back contact solar cell element.

主权项

1. A collector sheet for a solar cell which is disposed, as internal wiring of a solar cell module, on the rear surface side of a back contact solar cell element, the sheet comprising:
a circuit which is formed on the surface of a resin base material, and configured of a wiring section made of a metal and a non-wiring section; and an insulating layer which is formed on the circuit, wherein the insulating layer is provided with a white layer containing a white pigment.
