The optimization of dye-sensitized solar cells, especially the design nanoporous TiO2 film microstructure, is an urgent problem for high efficiency and future commercial applications. However, up to now, little attention has been focused on microstructure a cell modules. photoelectrode are discussed in this paper. photoelectrodes with three different layers, including layers small pore size films, larger light-scattering particles conducting glass desirable thickness, were designed...
A mesoporous SnO<sub>2</sub>electrode is firstly introduced in the CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub>perovskite solar cell as electron-transporting material and scaffold layer with over 10% power conversion efficiency.
In this paper, the photovoltaic performance and charge recombination of dye-sensitized solar cells (DSCs) based on nitrogen-doped TiO2 electrodes were investigated in detail. A negative shift flatband potential (Vfb) film was attributed to formation an O−Ti−N bond, it indicated that position edge Vfb is shifted negative, resulting improvement open circuit voltage for DSC with nitrogen doping.

Abstract Vanadium‐based compounds are identified as promising cathode materials for aqueous zinc ion batteries due to their high specific capacity. However, the low intrinsic conductivity and sluggish Zn 2+ diffusion kinetics seriously impede further practical application. Here, oxygen vacancies on NH 4 V O 10 is reported a high‐performing material via facile hydrothermal strategy. The introduction of vacancy accelerates charge transfer kinetics, reduces barrier ions, establishes stable...
