Abstract

Dye-sensitized solar cells (DSCs) were statistically investigated on TiO₂ thickness and dye-mass dependence. The DSC devices exhibited a trend of performance saturation from an approximately 15μm TiO₂ thickness with 10^-7mol/cm² dye-mass, which was estimated to be a maximum engineering condition required for effective charge-transfer kinetics in this investigation. The prominent factor for power conversion efficiency was increase of short-circuit current density by decrease of charge-transfer resistance with a heavy load of dye-mass. The dye-regeneration efficiency evaluated from a minimum electron density and a transferred counterpart ionic carrier density was approximately ranged between 1.5 and 3.0%.
