ORGANIC SOLAR CELL USING NANO MATERIALS OF CU AND CU2O

摘要

PURPOSE: An organic solar cell using copper and a copper oxide nanomaterial is provided to increase current density by amplifying the generation of electron-hole pairs. CONSTITUTION: An organic solar cell includes a bottom electrode, an electron transport layer, and a substrate. A hole transporting layer includes core-shell type nanoparticles made of Cu and CuO2. The hole transporting layer is formed by oxidizing the surface of Cu nanoparticles with a solution.
