Solar cell

A bypass diode includes a semiconductor substrate having a first surface and a second surface opposite to each other, a p electrode as a first conductive type electrode and an n electrode as a second conductive type electrode arranged on the first surface, a back surface electrode arranged on the second surface and having a polarity identical to that of the semiconductor substrate, a first oxide layer arranged on the first surface, and a second oxide layer arranged on the second surface.

A solar battery module includes a plurality of solar cells connected to one another and a plurality of spaces each provided between adjacent solar cells, the plurality of spaces including at least one repair space which is larger than other spaces. A replacement solar cell includes an electrode and an interconnector electrically connected to the electrode, the interconnector including a connecting portion, which is positioned with respect to a connecting portion of an interconnector electrically connected to an electrode of an existing solar cell adjacent to the repair space so that the connection by the interconnectors is performed in the repair space. A method of replacing a solar cell includes the steps of simultaneously removing a plurality of existing solar cells arranged between at least two repair spaces, and simultaneously mounting a plurality of replacement solar cells to the region from which the plurality of existing solar cells are removed.

A solar cell module includes a substrate, a plurality of solar cells arranged in a plane on the substrate, a connection member for electrically connecting the plurality of solar cells to each other to form a power generating circuit, and a single transparent cover sheet for covering the plurality of solar cells and the connection member.

A process for producing a solar cell comprises the steps of; forming at least one electrode on a first surface of a semiconductor substrate for constructing a solar cell, attaching a support substrate to the first surface of the semiconductor substrate on which said electrode is formed, and then processing the semiconductor substrate into a thin-film semiconductor substrate.

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.
