ORGANIC SOLAR CELL AND FABRICATION METHOD THEREOF

摘要

An organic solar cell of the present invention includes a substrate which has a plurality of convex units formed on a surface and a plurality of recess units formed in the other surface; and organic solar cell elements with are formed on either or both of the surfaces of the substrate. Accordingly, the present invention can increase the efficiency by widening the specific surface area of the organic solar cell, and implement two organic solar cells on a single substrate by forming the organic solar cell elements on the both surfaces of the substrate and implement a multi-layered structure.
