Electron collection in dye-sensitized solar cells (DSCs) is determined by a delicate equilibrium between electronic transport within the mesoporous oxide layers and recombination losses. While state-of-the-art DSC devices have shown quantitative collection under standard 1-sun conditions, the nonlinear nature of the trapping/detrapping dynamics in the oxide layer in relation to the overall electron density may result in suboptimal performance under the lower illumination levels commonly encountered in indoor settings. In this study, we thoroughly examine the key factors influencing electron collection with respect to light intensity using impedance spectroscopy and numerical analysis
