An aspect of the invention provides a solar cell that comprises a semiconductor substrate having a light-receiving surface and a rear surface; a first semiconductor layer having a first conductivity type; a second semiconductor layer having a second conductivity type, the first semiconductor layer and the second semiconductor layer being formed on the rear surface, and a trench formed in the rear surface, wherein the first semiconductor layer is formed on the rear surface in which the trench is not formed, and the second semiconductor layer is formed on a side surface of the trench in an arrangement direction in which the first semiconductor layer and the second semiconductor layer are alternately arranged and on a bottom surface of the trench.

Solar cell and method of manufacturing the same

A method of manufacturing a solar cell includes: forming a solar cell substrate having one main surface and the other main surface and having a p-type surface and an n-type surface which are exposed on one region and another region in the one main surface, respectively; forming seed layers in an electrically separated state on the p-type surface and the n-type surface, respectively; and forming a plated film on the seed layer on each of the p-type surface and the n-type surface by an electrolytic plating method.

Method of manufacturing solar cell

This solar cell apparatus is provided with: a long mounting frame having a guide rail section in an upper portion; and a fixing member, which is provided by being slid and moved in the longitudinal direction of the mounting frame, and which is fixed at a predetermined position of the mounting frame. The fixing member has: a base section that engages with the guide rail section; an upright wall section that is provided to stand on the base section; and insertion sections that extend from the upright wall section such that the insertion sections are inserted into a module frame of an eave-side solar cell module and a module frame of a ridge-side solar cell module.

Solar cell apparatus

A solar cell includes a solar cell substrate including a principal surface on which a p-type surface and an n-type surface are exposed, a p-side electrode formed on the p-type surface and including a first linear portion linearly extending in a first direction, and an n-side electrode formed on the n-type surface and including a second linear portion linearly extending in the first direction and arranged next to the first linear portion in a second direction orthogonal to the first direction. Corners of a tip end of at least one of the first and second linear portions are formed in a chamfered shape.

This photoelectric conversion device () is provided with: an n-type monocrystalline silicon substrate (); an IN layer () and an IP layer () formed on the back surface of the n-type monocrystalline silicon substrate (); an n-side electrode () containing an n-side underlayer (), an n-side primary conductive layer (), and an n-side protective layer (); and a p-side electrode () containing a p-side underlayer (), a p-side primary conductive layer (), and a p-side protective layer (). The n-side primary conductive layer () is formed in a manner so as not to cover the lateral surface of the n-side underlayer (), and is covered at the lateral surface by the n-side protective layer (). The p-side electrode () is formed in such a manner the lateral surface of the p-side underlayer () is not covered, and the lateral surface is covered by the p-side protective layer ().

Photoelectric conversion device and method for producing same

A solar cell module is provided with a plurality of solar cells and a wiring material. Each solar cell includes a p-side electrode and an n-side electrode arranged on one principal surface thereof. For each pair of adjacent solar cells, the wiring material electrically connects the p-side electrode of one solar cell and the n-side electrode of the other solar cell. Surface layers of the p-side electrodes and the n-side electrodes comprises, respectively, plating layers each containing at least one power-supplied point. The wiring material is bonded to the solar cells at regions each of which at least includes the power-supplied point.
