Electrode processes during electrodeposition, electropolishing and oxidation of niobium

The electrode processes occurring during the electrodeposition, electropolishing and oxidation of niobium are considered. The discharge of Nb(IV) complexes during Nb electrodeposition was studied by cyclic voltammetry. The anodic polarization curve on niobium in a mixture of acids H2SO4:HF (9:1) was obtained by chronopotentiometry method, the potential range at which the highest quality and speed of electropolishing is achieved was found. The film formation mechanism of niobium pentoxide Nb2O5 on niobium was studied by cyclic voltammetry.

In situ study of the film formation mechanism of organic–inorganic hybrid perovskite solar cells: controlling the solvate phase using an additive system

The role of the additive and solvate phases in the direct formation of perovskite crystals was revealed by in situ analysis during spin-coating condition.

Nucleation and crystal growth control for scalable solution-processed organic–inorganic hybrid perovskite solar cells

In this review, we provide an in-depth overview of perovskite film formation mechanism and highlight the important role of nucleation/crystal growth in perovskite photovoltaics by using scalable solution deposition techniques.
