There is disclosed a photovoltaic device 10 which comprises a light-transmittable base material 11, and a porous film 21b formed on the base material 11, in which a dye is absorbed, and the porous film 21b having the dye absorbed thereon contains the inventive titanium dioxide particle.
摘要:
The present invention aims to improve short circuit current density and photo-to-electron conversion efficiency without thickening the whole thickness of the device and increasing the number of manufacturing processes. A photovoltaic device comprises a light-transmittable base material 31, and a porous film 41b formed on the base material and adsorbing a dye. The porous film 41b adsorbing the dye 41d contains a titanium dioxide particle 41c containing aluminum oxide. The titanium dioxide particle 41c is a mixed particle of a first titanium dioxide particle doped with aluminum oxide and a second titanium dioxide particle not doped with aluminum oxide. The first titanium dioxide particle contains 70 to 95 wt. % anatase crystal, and a specific surface area by the BET method of the titanium dioxide particle 41c is 35 to 65 m2/g, and an adsorbing amount of oil of the titanium dioxide particle 41c measured by the method based on JIS K5101 is 55 to 75 ml/100 g.

A percutaneous absorption preparation which is excellent in the skin penetration of a non-narcotic analgesic buprenorphine and can sustain a high blood level in a stable state over a long period of time is provided. The percutaneous absorption preparation for administrating buprenorphine hydrochloride and/or buprenorphine, which comprises a support having on one surface thereof a plaster layer containing a pressure-sensitive adhesive, buprenorphine hydrochloride and/or buprenorphine, and a penetration enhancer, wherein the penetration enhancer comprises a combination of a monoglyceride of a fatty acid having 6 to 8 carbon atoms and isopropyl myristate, and the plaster layer contains at least 10% by weight of a monoglyceride off fatty acid having 6 to 8 carbon atoms and at least 5% by weight off isopropyl myristate, with the proviso that the content of the whole penetration enhancer ranges from 25 to 50% by weight. The combined use of the fatty acid monoglyceride and isopropyl myristate as a penetration enhancer synergistically elevates skin penetration of buprenorphine hydrochloride and/or buprenorphine.
摘要:
Pyrogenically produced silicon dioxide doped with aluminum oxide by means of an aerosol is produced by introducing an aqueous aerosol of an aluminum salt into the flame of a pyrogenic silica producing flame hydrolysis method or a flame oxidation method. The silicon dioxide doped with Al2O3 by means of an aerosol may inter alia be used in the production of inkjet paper or inkjet films.
