TLDR
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

TL;DR: Time-resolved emission and absorption spectroscopy is used to study the photoinduced dynamics of forward and back electron transfer processes taking place between a recently synthesized series of donor-(π-spacer)-acceptor organic dyes and semiconductor films, implying that smaller electron injection rates and smaller extinction coefficients result in reduced dye sensitized solar cell (DSSC) conversion efficiencies.

Application of π-Extended Ferrocene with Varied Anchoring Groups as Photosensitizers in TiO2-Based Dye-Sensitized Solar Cells (DSSCs)
TL;DR: Two new compounds, FcCH=NC(6)H(4)COOH (1) and Fc CH=NCH( 2)CH(2)OH (2) (Fc=C(5)H (4)FeC (5) H(5)), have been synthesized and characterized by elemental analyses, IR and (1]H NMR spectroscopy, and ESI-MS.

Ruthenium(II) complexes bearing a naphthalimide fragment: a modular dye platform for the dye-sensitized solar cell.
TL;DR: It is shown that substitution of the pyridine ring of the C^N ligand with conjugated groups can enhance molar absorption extinction coefficients, while the electron density imparted on the metal center is alleviated by the 1,8-naphthalimide fragment.

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.
