Probing Energetics of Molecule-Semiconductor Interfaces for Nanocrystalline TiO-2 Solar Cells

摘要

There is interest in maximizing photocurrents and photovoltages of dye-sensitized nanocrystalline solar cells by tuning the conduction band edge energy with respect to the excited state of the sensitizer. Electrolyte modification of dye-sensitized nanocrystalline solar cells provides quantitative control of molecular excited-state transfer to ground state products or to charge-separated states via interfacial electron transfer.
