Interconnector and electronic device element with the interconnector

摘要

An interconnector includes a first connecting portion connected to a front surface electrode of a solar cell, a second connecting portion connected to a rear surface electrode of another solar cell connected in serial direction, and a stress relief portion formed between the first connecting portion and the second connecting portion for absorbing displacement. The width of the first connecting portion in the parallel direction is made smaller than the width of the stress relief portion in the parallel direction. By this structure, the width of the front surface electrode of the solar cell can be reduced, the effective light receiving area of the solar cell can be increased, and therefore the efficiency in generating power can be improved.
