A suite of DSSC characterization experiments was developed which could be rapidly performed on a standard two electrode sandwich cell. In combination with a novel technique for mediator replacement without cell disassembly, this suite was utilized to probe the influence of several parameters on DSSC functioning in order to identify limitations of cells mediated by cobalt complexes. The results clearly implicate diffusion of cobalt(III) to the cathode as frequently rate-limiting.The two-electrode mode of a potentiostat is attained by shorting the reference and auxiliary electrode wires together. ... wire of the potentiostat was connected to the non- operational side of the photoanode and the instrument behaved as a anbsp;...
