Titanium dioxide (TiO 2) has been the most intensively investigated binary transition metal
oxide in the past four decades as indicated by Figure S1. Furthermore, the annual number of …

The carbon neutral process for energy conversion is of utmost importance, in this context
photovoltaics, especially dye sensitized solar cells (DSSCs) are a viable alternative. Few …

Electrochemical impedance spectroscopy, photoelectron spectroscopy, and Kelvin probe
measurements on various TiO2 single-crystal surfaces show that the position of the Fermi …

Dye-sensitized solar cells (DSSCs) feature low cost, stability, and environment friendliness
and are thus a promising substitute for traditional silicon solar cells. DSSCs have received …

This paper reviews selected problems, which appear in literature dealing with TiO2, SnO2,
and ZnO. Some of them have more universal impact to semiconductor electrochemistry. The …
