Abstract

Electron lifetime and diffusion coefficient measurements in highly efficient porphyrin-sensitised TiO2 solar cells showed reduced electron lifetime, and consequently, lower photo-induced electron density under illumination compared to commonly used ruthenium dye (N719)-sensitised solar cells, which is proposed to be the origin of the generally lower open circuit voltage.
