In a solar cell, at least one of reinforcing material and buffering material is provided at least partially on at least one of a back surface, a front surface and a side surface of the solar cell. With these reinforcing material and/or buffering material, occurrence of cell fracture due to load imposed by external force can be decreased.

Solar cell and method of producing the same

The object of the invention is to provide a solar panel and a method for manufacturing the same, wherein the manufacture of the solar panel for use in space and repair work thereon can be performed easily and in little time. An entirety of the solar panel is configured by detachably linking a plurality of unit solar cell modules, which include a plurality of solar cells and connection wires for connecting the solar cells, and electrically connecting the unit solar cell modules to one another. Thus, a solar panel can be easily fabricated by combining standardized unit solar cell modules. Moreover, by simply mechanically connecting the unit solar cell modules, they can be electrically connected, and thus the time necessary for manufacture or repair of solar panels can be shortened.

Solar panel for space and method for manufacturing the same

A powder glass solution is applied on top of a solar cell with electrodes formed thereon, and solvent is volatilized, followed by baking process, by which a glass is directly formed on the top of the solar cell . In this way, the alignment between solar cell and glass as well as the finish work of removing overflowed adhesive are eliminated. Also, by selecting a powder glass having a coefficient of thermal expansion generally similar to that of a P-type silicon substrate , distortion by heating due to abrupt temperature changes is reduced. Thus, cost reduction and reliability improvement can be fulfilled.

Covered solar cell and manufacturing method thereof

A nanometer-size quantum thin line is formed on a semiconductor substrate of a Si substrate or the like by means of the general film forming technique, lithographic technique and etching technique. By opportunely using the conventional film forming technique, photolithographic technique and etching technique, a second oxide film that extends in the perpendicular direction is formed on an Si substrate. Then, by removing the second oxide film that extends in the perpendicular direction, a second nitride film located below the film and a first oxide film located below the film by etching, a groove for exposing the Si substrate is formed. Then, a Si thin line is made to epitaxially grow on the exposed portion of the Si substrate. The quantum thin line is thus formed without using any special fine processing technique. The width of the groove can be accurately controlled in nanometers by controlling the film thickness of the second oxide film that is formed by oxidizing the surface of the second nitride film.
