Abstract Two phenoxazine (POZ)-based organic D–π–A sensitizers (POZ-1 and POZ-2) were synthesized. Then these two dyes were applied in dye-sensitized solar cells (DSSCs) to investigate the influence of different conjugated direction, extra phenyl ring and alkyl chain on the light-harvesting, energy level and photovoltaic properties through a joint spectral, electrochemical and photovoltaic study. The result shows that dye POZ-2 exhibits ...
