Junctions between p and n type semiconductors are the fundamental structure upon which nearly all semiconductor technology is based. The stabilization of such junctions within a solution-processed semiconductor has great potential in the continuing expansion of organic electronic and/or photonic devices. We describe a process for forming fixed polymer homojunctions that demonstrate stability and high rectification ratios. This method shows promise beyond light-emitting displays for a range of device architectures for rectification, amplification, and photovoltaic applications.
