We also investigate the spectroscopic and electrochemical properties of these dyes and their application to dye-sensitized solar cells (DSSCs). The trans-cis isomerization of the azobenzene bridge permits regulation of the photovoltaic behaviour in the DSSCs containing iodine- and cobalt-based redox electrolytes. The iodidie/triiodidie redox shuttle is suitable for DMAC-DSSCs, whereas the cobalt redox mediator is optimal for DPAC-DSSCs. DMAC- and DPAC-DSSCs yield power conversion efficiencies (PCEs) up to 1.99 % and 1.08 % under one sun illumination, when the solar cells are at the photostationary (PS) state.
