Oxidative Chemical Vapor Deposition of Neutral Hole Transporting Polymer for Enhanced Solar Cell Efficiency and Lifetime

The concept of a neutral hole‐transporting polymer is realized for the first time, by integrating patterned Cl−‐doped poly(3,4‐dimethoxythiophene) thin films into organic solar cells through a vacuum‐based polymer vapor printing technique. Due to this novel polymer's neutrality, high transparen...

Description
Summary:The concept of a neutral hole‐transporting polymer is realized for the first time, by integrating patterned Cl−‐doped poly(3,4‐dimethoxythiophene) thin films into organic solar cells through a vacuum‐based polymer vapor printing technique. Due to this novel polymer's neutrality, high transparency, good conductivity, and appropriate energy levels, the solar‐cell efficiency and lifetime are significantly enhanced.
