摘要: In a photoelectric conversion device having numerous crystalline semiconductor grains deposited on a substrate, the substrate includes an aluminum layer or an aluminum alloy layer, an intermediate layer, and a base material layer, in which the intermediate layer is arranged such that it is composed mainly of one or a plurality of elements selected from among nickel, titanium, chromium, and cobalt. With the constitution as above, it is possible to suppress reaction between the aluminum electrode layer and the base material layer, thereby maintaining the high adhesiveness of the aluminum electrode layer. A photoelectric conversion device with high reliability and high conversion efficiency is therefore realized.

摘要: This photoelectric conversion device comprises a lower electrode, numerous p-type crystalline semiconductor particles deposited thereon, an insulator formed among the crystalline semiconductor particles, and a n-type semiconductor layer formed on the side of the upper portions of the crystalline semiconductor particles. The insulator is formed of a translucent material, and the surface of the lower electrode has been subjected to roughening treatment. Roughening the surface of the lower electrode allows light incident on the surface of the lower electrode to be scattered and directed to the crystalline semiconductor particles so that the photoelectric conversion efficiency is improved.

摘要: Plasma is generated from a plasma generating gas comprising an inert gas and hydrogen gas. Silicon material is passed through the plasma and heated so as to form a crystalline silicon particle containing hydrogen at a concentration of 1×1016-1×1020. A great number of the crystalline silicon particles of p-type or n-type are deposited on a substrate as the electrode of one side. An insulator is formed among the crystalline silicon particles on the substrate, and a n-type or p-type semiconductor layer is formed over the crystalline silicon particles, thereby fabricating a photoelectric conversion device. The photoelectric conversion device using the crystalline silicon particles exhibits high photoelectric conversion efficiency.

摘要: In a method for manufacturing a granular silicon crystal by allowing silicon melt in a crucible to be granularly discharged and fallen from a nozzle part composed of silicon carbide or silicon nitride, and cooling and solidifying the granular silicon melt during falling, a carbon source is added when the nozzle part is composed of silicon carbide, and a nitrogen source is added when the nozzle part is composed of silicon nitride, to the silicon melt in the crucible. Thereby, melt droplets of uniform size can be generated, so that granular silicon crystals having narrow variations in particle size can be manufactured at high productivity and superior reproducibility.
