Two water/alcohol soluble conjugated polymers (WSCPs), based on naphthalenediimide and amino-functionalized 3,4-(propylenedioxy)thiophene, were synthesized via direct arylation polycondensation (DArP). The polymers worked well as electron transporting layers (ETLs) for fullerene-based and fullerene-free organic solar cells (OSCs), presenting an enhancement by above 40% compared to the control devices, respectively. The doping properties and high electron mobilities of these WSCPs endow them with high performance. The research study developed an effective method to synthesize ETLs for highly efficient OSCs, which was rarely reported.
