Water/alcohol soluble conjugated polymers for the interface engineering of highly efficient polymer light-emitting diodes and polymer solar cells

Abstract

Water/alcohol soluble conjugated polymers (WSCPs), which can be processed from water/alcohol and other polar solvents, are suitable for the solution processing of multi-layer organic electronic devices. By using a thin layer WSCP as the cathode interfacial material, the resulting polymer light-emitting diodes (PLEDs) and polymer solar cells (PSCs) exhibited significant enhancements in their device performances. In this Feature Article, the authors aim to introduce a brief review of the recent developments and applications of WSCPs in highly efficient multi-layer solution processed PLEDs and PSCs.
