摘要:
An interconnector includes a strip-shaped and electrically conductive member for electrically connecting respective electrodes to each other of solar cells adjacent to each other. The conductive member includes a stress relief part that is planer and has a notch forming an obtuse angle at a lateral end or has a linear lateral end. This structure remarkably alleviates a stress due to a difference in thermal expansion coefficient between the interconnector and the solar cells, so that a warp occurring to the solar cells is reduced and the reliability of connection between the interconnector and the solar cells is improved.

Management of a manufacturing process also in assembling a solar battery module is facilitated. A solar battery module evaluation apparatus includes a power supply unit, a camera, and a processing unit. The power supply unit supplies electric power. The processing unit outputs pattern information indicating whether a solar battery module is defective or not, based on data of an image picked up by the camera, the image being an optical image that appears as a result of supply of electric power to the solar battery module for light emission through electroluminescence phenomenon.

An interconnector includes a strip-shaped and electrically conductive member electrically connecting respective electrodes of adjacent solar cells, the conductive member includes a plurality of planar stress relief parts and the stress relief parts are formed at equal pitches. With this structure, a stress due to a difference in thermal expansion coefficient between the interconnector and the solar cell is uniformly alleviated, so that the warp occurring to the solar cell is reduced and the reliability of the connection between the interconnector and the solar cell is improved.

A solar cell includes a semiconductor substrate having a first main surface. On the first main surface, a bus bar electrode and a plurality of linear finger electrodes extending from the bus bar electrode are provided. The bus bar electrode includes a first connecting portion to be connected to an interconnector and a first non-connecting portion without connected to the interconnector. The first connecting portion and the first non-connecting portion are alternately arranged. An interconnector-equipped solar cell, a solar cell string and a solar cell module use this solar cell.
