Abstract: The present invention discloses a method for improving solar energy conversion efficiency using metal oxide photocatalysts having an energy band of core-shell structure for ultraviolet (UV) ray and visible light absorption, comprising a first process of forming a nanoparticle thin film layer; a second process of preparing a core-shell metal oxide on metal oxide nanoparticles by a plasma reaction under a hydrogen and nitrogen gas atmosphere, and a third process of depositing a transition metal on surfaces of core-shell metal oxide nanoparticles to produce a photocatalyst for energy conversion. A great amount of oxygen vacancies is formed in a shell region by the core-shell metal oxide to achieve effects of improving transfer ability of electron-hole pairs excited by light, and extending a wavelength range of absorbable light to a visible light region by changing a band-gap structure.

Abstract: Disclosed is a technique for fabricating a bio-photovoltaic cell which includes coupling graminoids extracted from natural grasses to a semiconductor electron acceptor, on which plasmonic silver nanoparticles are aligned, by using an organic ligand material. More particularly, disclosed is a technique for fabricating a new renewable energy generation device useable for fabrication of high efficiency bio-photovoltaic cells by improving a photo-electron generation rate of graminoids through a surface plasmon effect of silver nanoparticles and increasing an effective photo-electron amount transferred to the electron acceptor due to optimized bonding between a photo sensitizer and an electron acceptor.
