Polymer Nanostructure Approach for Photoelectric Solar Energy Conversions

摘要

This presentation provides a brief overview on the mechanisms, history, current status, and future prospective of polymer or 'soft materials' based photoelectric conversion materials, with a focus on a block copolymer nanostructure approache to address the loss issues in organic or polymer based solar cells. For instance, a DBfA type of block copolymer exhibits a two orders of magnitude enhancement of photoelectric conversion efficiency over its corresponding D/fA blend system. Such enhancement is attributed mainly to the DBfA self-assembled solid state nanostructure that minimizes the carrier losses.
