Interconnect sheet, solar cell with interconnect sheet, solar module, and method of producing solar cell with interconnect sheet

Abstract

An interconnect sheet (10) with insulating base material (11) on which interconnects (16) for electrically connecting a plurality of back surface electrode type solar cells (20) are placed, said interconnect sheet (10) being provided with a plurality of cell placement sections (10a) on which back surface electrode type solar cells (20) are placed, and having an insulating layer (101) provided on the cell placement side between neighboring cell placement sections (10a). Thus, disclosed is an interconnect sheet (10) used for back surface electrode type solar cells, which can limit unnecessary contact occurring between the back surface electrode type solar cells (20) placed on the interconnect sheet (10) and the interconnects (16) of the interconnect sheet (10). Further disclosed are a solar cell with the interconnect sheet, a solar module, and a method of producing the solar cell with the interconnect sheet.

Description

technical field [0001] The present invention relates to a wiring board, a solar battery cell with a wiring board, a solar battery module, and a method for manufacturing a solar battery cell with a wiring board. Background technique [0002] In recent years, due to the depletion of energy resources, CO in the atmosphere 2 The development of clean energy is highly expected due to the increasing global environmental problems, and in particular, photovoltaic power generation using solar cell modules has been developed and put into practical use as a new energy source, and is advancing along the road of development. [0003] As a solar cell constituting such a solar cell module, a double-sided electrode type solar cell has conventionally become the mainstream. The double-sided electrode type solar cell conducts electricity opposite to the silicon substrate by diffusing the light-receiving surface of a single crystal or polycrystalline silicon substrate, for example. Type impurit...

[0015] In the latter process and the variation in the installation environment, thermal shrinkage and thermal expansion of the wiring board may occur due to heat treatment in the above-mentioned process, for example, and the position of the electrode of the back electrode type solar cell relative to the wiring of the wiring board may be affected. deviation will occur

In addition, in the above-mentioned sealing step, the positional deviation between the wiring board and the back electrode type solar cell panel may also be caused due to the fluidized sealing material.
