A Method to Determine the Optimal Solids Content of TiO2 in DSSC Working Electrode

The way to determine the optimal solids content of TiO2 in DSSC working electrode was discussed. As a mathematical proof of the optimal conclusion extracting from the complex working mechanism of DSSCs and accidental factors, the equivalent circuit parameters of each curve are estimated corresponds to the equivalent circuit method first. And then, the trends in each parameter are analyzed. According to these trends, the optimal solids content of TiO2 are optimal identified
