A critical review of light-driven interfacial charge-transfer reactions of transition-metal compounds anchored to mesoporous, nanocrystalline TiO2 (anatase) thin films is described.Abstract:
A critical review of light-driven interfacial charge-transfer reactions of transition-metal compounds anchored to mesoporous, nanocrystalline TiO2 (anatase) thin films is described. The review highlights molecular insights into metal-to-ligand charge transfer (MLCT) excited states, mechanisms of interfacial charge separation, inter- and intra-molecular electron transfer, and interfacial charge-recombination processes that have been garnered through various spectroscopic and electrochemical techniques. The relevance of these processes to optimization of solar-energy-conversion efficiencies is discussed (483 references).read more

Slow excited state injection and charge recombination at star-shaped ruthenium polypyridyl compounds--TiO2 interfaces.
TL;DR: The excited states of two star-shaped nanometre-sized ruthenium polypyridyl compounds were largely unchanged when anchored to nanocrystalline TiO(2) thin films due to a highly symmetrical and rigid ligand structure that isolated the chromophoric core from the semiconductor.

Detailed Balance Limit of Efficiency of p‐n Junction Solar Cells
TL;DR: In this article, an upper theoretical limit for the efficiency of p−n junction solar energy converters, called the detailed balance limit of efficiency, has been calculated for an ideal case in which the only recombination mechanism of holeelectron pairs is radiative as required by the principle of detailed balance.
