METAL OXIDE SEMICONDUCTOR-NANOCARBON CONSOLIDATED CORE-SHELL QUANTUM DOTS AND ULTRAVIOLET PHOTOVOLTAIC CELL USING IT AND A FABRICATION PROCESS THEREOF

摘要

PURPOSE: An oxide semiconductor - nano carbon nucleus - shell integrated quantum dot is provided to maximize the chemical combinding number of metal-oxide-carbon(nano carbon) within oxide semiconductor by binding nano carbon with an excellent electrical characteristic to an oxide semiconductor with a chemical method. CONSTITUTION: An oxide semiconductor - nano carbon nucleus - shell integrated quantum dot has oxide semiconductor which comprises light absorption layer as a nucleus and cover the core with nano carbon in a form of shell. The oxide semiconductor is zinc oxide. The nano carbon is graphene or fullerene. Connect a oxide semiconductor which comprised nucleus and a nano carbon which comprises the shell through a chemical bond of oxygen atom. A size of the quantum dot is 8-15nm. An ultraviolet ray solar cell has oxide semiconductor - nano carbon integrated nucleus - shell quantum dot as a single active layer.
