Abstract

The temporal response of a biomimetic dye-sensitized solar cell (DSSC) is critically linked to the intensity of the incident light. When a DSSC is partially illuminated and the incoming light is of low intensity, the response time of the cell is prolonged dramatically. In this report, the major components of the DSSC are investigated to find the source and to provide a model of the driving mechanisms behind this delay. For low light level conditions, only deep traps states of the TiO₂ layer participate in electron transport resulting in a slow temporal response. Increasing the illumination level thus increases the conductivity of the TiO₂ electrode by filling these trap states and increases the response time. This study shows a strong correlation between the light intensity, active area and excitation wavelength on the temporal response time of a DSSC.
