Abstract

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).
