Latest Patents

One of Oyama's latest patents is a method of preparing a semiconductor layer for an optical transforming device. This invention involves forming a semiconductor layer for a photoelectric transfer device that creates a p-n junction with a large surface area and uniform film pressure. The process occurs in an atmosphere under normal pressure for several minutes. The semiconductor layer is composed of a compound semiconductor derived from a Group II element, such as cadmium, zinc, or mercury, combined with a Group VI element like sulfur or tellurium. Additionally, a semiconductor film is formed on a substrate by pyrolytically decomposing an organometallic compound containing a II-VI group atom bond.

Another significant patent by Oyama relates to the manufacturing method of a compound semiconductor thin film derived from a metal sulfide. This metal sulfide is produced through the thermal decomposition of a sulfur-containing metal organic compound. The compound includes at least one functional group with a metal atom selected from copper, zinc, cadmium, mercury, or lead, along with at least one sulfur atom. The resulting metal sulfides are of high purity and density, making them suitable for various photoelectric devices. Notably, the photoelectric conversion efficiency of a CdS/CdTe system thin film compound semiconductor solar cell can be significantly improved by using a CdS thin film as the window of the solar cell.
