Science, 1980
The electron-hole pair formation that occurs at the interface between a semiconductor and a solution upon absorption of light leads to oxidation or reduction reactions of solution species. The principles of such photodriven processes are described as well as applications of semiconductors in electrochemical cells and as particulate systems for carrying

Synthetic Semiconductor Photoelectrochemistry
The Chemical Record, 2021AbstractIn the field of synthetic organic chemistry, photochemical and electrochemical approaches are often considered to be competing technologies that induce single electron transfer (SET). Recently, their fusion, i. e., the “photoelectrochemical” approach, has become the focus of attention. In this approach, both solar and electrical energy are used

Photoelectrochemistry of metallochlorophylls
Coordination Chemistry Reviews, 1985Abstract Photoinduced electron transfer from eleven metallochlorophyll a (MChl a) monolayers to a SnO2 substrate was investigated photoelectrochemically. Six MChl as [M = Pd(II), Cu(II), Hg(II), H2(II), Mg(II), and Zn(II)] gave measurable photoeffects. For the latter three pigments, two-dimensional dilution of the monolayer led to an enhancement of
