Interconnector, solar battery string using such interconnector, method for manufacturing such solar battery string and solar battery module using such solar battery string

Abstract

An interconnector is provided with a strip-shaped conductive member (3) which electrically connects electrodes of adjacent solar battery cells. The conductive member includes a stress relief section (X1), which is planar and has a notch to constitute a obtuse angle at a side end section or has a linear side end section. Since stress due to difference between the thermal expansion coefficient of the interconnector and that of the solar battery cell is remarkably relaxed by such constitution, warping generated by the solar battery cell is reduced and reliability in connection between the interconnector and the solar battery cell is improved.

Description

Interconnector, solar cell string using the same, and manufacturing method thereof, and solar cell module using the solar cell string technical field The present invention relates to an interconnector that connects solar cells to each other, to a battery string using the interconnector, a method of manufacturing the solar cell string, and a solar cell module using the solar cell string. More specifically, the present invention devises an interconnector that can reduce warpage occurring in each solar cell when connecting solar cells with the interconnector. Background technique For solar cells that directly convert solar energy into electrical energy, their availability has recently been expected to significantly increase as a next-generation energy source - especially in view of global environmental factors. Solar cells are classified into various categories such as those using compound semiconductors and those using organic materials. Recently, most solar cells use silic...

Problems solved by technology

Moreover, the warping that occurs in solar cells leads to transport errors and cell ruptures in the transport systems involved in automated module manufacturing lines

Also, in a state where a plurality of solar cells are electrically connected by interconnectors (hereinafter referred to as "strings"), if each solar cell has warpage, local strong force applied to the solar cells that are part of the battery string, and cause the solar cells to rupture
