INTER-DIFFUSED ORDERED BULKHETEROJUNCTION STRUCTURE OF ORGANIC PHOTOVOLTAICS SATISFYING BOTH OF EXITON DISSOCIATION AND CHARGE TRANSPORT

摘要

and forming a first polymer on a substrate according to the present invention , for the first polymer nano by performing the imprinting by forming a concave-convex structure , comprising the steps of forming a charge transfer path from the electrode , and performing a first annealing heat treatment for the first polymer and the second polymer in the concave-convex structure by heat evaporation forming on , by performing the second annealing heat treatment for the first and the second polymer , the first polymer and the second polymer is a charge transfer path , while maintaining the concave-convex structure by the mutual diffusion only in the vicinity of the boundary the inter-diffusion -type heterojunction solar cell shaping method is provided comprising the steps of to . ;
