TL;DR: In this paper, the authors presented a model for the structural, spectroscopic, and catalytic properties of Carbonic Anhydrase. But they did not discuss the role of carbon dioxide in photo-and electrochemical reduction in photosynthesis.

TL;DR: In this paper, the kinetics of interfacial electron transfer reactions associated with the sensitization process were discussed, and the authors achieved incident photon to current conversion yields of more than 60% in the visible.
Abstract: The sensitization of semiconductors is a fascinating domain of present research which has found important applications in different areas such as artificial photosynthesis. This lecture discusses first the kinetics of interfacial electron transfer reactions associated with the sensitization process. The advent of colloidal semiconductors combined with ultrafast laser techniques has permitted the unravelling of the dynamics of the charge transfer reactions. In the case of 100 A sized TiO2 particles the electron injection from the excited sensitizer in the conduction band was found to be several orders of magnitude faster than the back reaction. This effect has been exploited by us in the conversion of light into electricity or chemical fuels. Using rough polycrystalline TiO2 layers we have achieved incident photon to current conversion yields of more than 60% in the visible Such high values are unprecedented and constitute a breakthrough in the sensitization of large band gap semiconductor devices.
