Organometallic halide perovskites have attracted tremendous attention for solar applications. In addition to traditional solid-state photovoltaic device, the photoelectrochemical cell (PEC), which produces a photovoltage at a semiconductor/liquid junction, is also attractive due to its simple cell structure and has been an efficient method for characterizing the quality of photoactive materials. However,...
A retrospective overview of electrochemical studies of semiconductor nanocrystals (NCs) is given. The electrochemical behavior of monodisperse NCs in a non-aqueous supporting electrolyte can be derived from the electron quasiparticle energy and the electron self-energy. Coulomb blockade can sometimes be observed in Si NCs if the charged NCs are stable. Many NCs, such as Ge, CdS, CdSe, PbS and core-shell...
This book presents the fundamentals of bonding in polyoxometalates and related oxides based on classical bonding concepts and the bond valence model. The in-depth treatment includes a revision of the procedure for the determination of the parameters of bond length-bond valence functions, the application of the bond valence model to polyoxometalates and related oxides, and the explanation of the distribution...
