摘要： This invention relates to a photovoltaic device, such as a solar cell or a photosensor, which comprises an amorphous silicon semiconductor photosensitive layer and, as disposed on respective sides thereof, a transparent electrode and a rear electrode. The rear electrode is a multi-layer structure constructed by alternately successive depositions, each in a thickness of 0.3 to 50 nm, of two or more metals selected from the group consisting of Cu, Ag, and Au. In using such a Cu/Ag multi-layer structure or an Au/Ag multi-layer structure as the rear electrode, the thickness of each Cu or Au layer is controlled at 0.3 to 20 nm and that of each Ag layer at 1 to 50 nm. The total thickness of the rear electrode is 20 nm to 1 .mu.m. This construction insures improved photoelectric conversion efficiency and improved reliability of the device.

摘要： The invention provides a temperature switch material capable of detecting a very low temperature not higher than 150 K. It also provides a light switch material for detecting light in the ultraviolet region. It further provides a switch material suited for use as a substrate for thin oxide layer formation thereon. The switching material utilizes an abrupt change in photoelectric current as produced upon phase transition of SrTiO.sub.3 at a low temperature. The photoelectric switch or temperature switch utilizes the change in photoconduction spectrum upon irradiation of SrTiO.sub.3 with light in the 3 eV-5 eV ultraviolet region. A switch is available by varying the intensity of irradiating light thereby controlling the transition temperature.

摘要： A process for preparing sucrose fatty acid esters by reacting sucrose and a fatty acid alkyl ester in an aqueous reaction system in the presence of a catalyst, adding water to the reaction mixture to dissolve it, adjusting the reaction mixture to a neutral ph region, adding a neutral salt to the solution to precipitate the sucrose fatty acid esters, separating and washing the precipitate with an acidic water, and subjecting the washing liquid to ultrafiltration. The precipitate washed with the acidic water is spray-dried in the form of an aqueous slurry to give a dry powder of the sucrose esters having low HLB, and the concentrate obtained by ultrafiltration is spray-dried to form a dry powder of the sucrose esters having high HLB, and the liquid obtained by separating the precipitate is contacted with a reverse osmosis membrane to recover sucrose. According to the invention, purifed sucrose fatty acid esters can be obtained without using an organic solvent, while sucrose can be recovered in high yield.
