Photocurrents generated by thick, strongly absorbing, dye-sensitized cells were reduced when the electrolyte Iodine concentration was increased. Electron diffusion lengths measured using common transient techniques (Ln) were at least two times higher than diffusion lengths measured at steady state (LIPCE). Charge collection efficiency calculated using Ln seriously overpredicted photocurrent, while LIPCE correctly predicted photocurrent. This has implications for optimizing cell design.
