We present a methodology to measure current resultant from intermittent light studies conducted on dye-sensitized solar cells (DSSCs) and resultingly calculate electron dispersive kinetic values. We found these values to primarily support previously collected data.4 Analysis of additional intermittent patterns (1 minute exposed to light/10 seconds unexposed to light and vice-versa) lead to collected lifetime values (K) shorter than previously investigated intervals (119 and 111 ms compared to 177 and 298 ms). The effect of Li+ electrolyte was also investigated, resulting in larger lifetime values (K) for every intermittent pattern (101 to 130 ms; 116 to 163 ms; 86 to 203 ms; 77 to 121 ms).
