Title: Hikaru Kobayashi: Inventor of a Zinc Oxide Solar-Cell Laminate
Introduction
Hikaru Kobayashi is an inventor based in Tokyo, Japan, with 1 patent. His patent concerns materials for organic thin-film solar cells.
Latest Patents
Kobayashi’s patent, “Zinc oxide laminate for an organic thin film solar cell,” describes a laminate combining a light-transmissive electrode layer with a zinc oxide electron-transport layer. The invention specifies a zinc deposition amount of 20.0 to 120.0 mg/m². It also sets a limit for an S value derived from separating the zinc oxide layer’s oxygen 1s spectrum, measured by X-ray photoelectron spectroscopy, into three peaks. The specified S value is no more than 0.90, based on the areas of peaks within defined binding-energy ranges.
