摘要:
A method for producing a thin film solar cell includes preparing a substrate of a low purity material and having opposed front and rear surfaces; forming an insulating film on the front surface of the substrate; forming a second conductivity type active layer of a high purity material on the insulating film with a front surface exposed; forming a second conductivity type semiconductor region within the active layer, reaching the front surface, to produce a p-n junction for light-to-electricity conversion; forming an anti-reflection film on the front surface of the active layer, the anti-reflection film reducing reflection of incident light; forming a surface electrode in contact with the front surface of the active layer; adhering the front surface side of the active layer to a supporting plate and selectively etching the low purity substrate from the rear surface to form a supporting substrate supporting the active layer; and forming a rear electrode on the rear surface of the supporting substrate contacting the active layer.

A method for producing a thin-film solar cell includes successively depositing a lower anti-reflection film having a relatively large etching rate in a prescribed etchant and an upper anti-reflection film having a relatively small etching rate in the prescribed etchant on a photosensitive surface of a semiconductor substrate; patterning the upper anti-reflection film to form an aperture; and etching the lower anti-reflection film using the patterned upper anti-reflection film as a mask.
摘要:
A thin-film solar cell includes a thin active layer of high purity material having opposed front and rear surfaces for light-to-electricity conversion, a structure for supporting the thin active layer, and a rear electrode in contact with the rear surface of the active layer. The supporting structure includes a supporting substrate of a low purity material having opposed front and rear surfaces, on the front surface of which the rear surface of the active layer is disposed, and an insulating barrier layer interposed between the front surface of the supporting substrate and the rear surface of the active layer. The barrier layer prevents impurities in the supporting substrate from diffusing into the active layer. Since the supporting substrate comprises a low purity material, the quantity of the expensive high purity material can be reduced by reducing the thickness of the active layer, resulting in low production costs. Since the supporting substrate is present on the rear surface of the active layer, a surface electrode disposed on the front surface of the active layer is exposed. Therefore, when a solar cell module is fabricated using a plurality of the solar cells, a wire bonding process for connecting adjacent solar cells is easily carried out.

A thin-film solar cell includes a thin-film active layer with a p-n Junction and a heat-resistant substrate for mechanically supporting the active layer, which substrate is formed by a plasma coating method. In the plasma coating method, a source material of the substrate is melted with a high-temperature plasma and sprayed onto a base plate by a high-speed gas jet. Since the substrate formed by the plasma coating method is porous, even if an inexpensive material including a lot of impurities is used as a material of the substrate, the impurities are collected in pores of the substrate and never sprout out of the substrate breaking through the thin-film active layer.

摘要:
The present inventors focused on certain nutritional compositions known to have activity of controlling blood glucose levels. These foods were administered to rats for long periods, and real-time PCR was used to analyze the expression of genes associated with lipid metabolism in the liver and adipose tissues. As a result, the present inventors found that the expression of the PPARα gene is enhanced by these foods, and that this is accompanied by suppressed expression of fatty acid synthase and enhanced expression of a group of PPARα target genes associated with fatty acid metabolism. The present inventors also confirmed the effect of these foods in enhancing the expression of PPARγ and adiponectin, and discovered that these foods have the activity of enhancing the production of PPAR and PPAR-associated factors.

A mark issuing server operated by a mark issuer manages mark information collectively. A terminal of a user sends an information providing request to an information providing server of an information provider, and issues a mark issuing request to the mark issuing server on the basis of the information providing request. The information providing server searches for information corresponding to the information providing request from the terminal of the user, and provides the terminal of the user with information including requested information and location information of the mark issuing server. The mark issuing server determines validity of information provided from the information providing server on the basis of the mark issuing request, and sends a mark to the terminal of the user when the validity is verified, and the terminal of the user displays the mark with the information provided from the information providing server.
