TL;DR: In this paper, it was shown that the color change results from silver oxidation to silver iodide, due to a reaction with iodine in methyl ammonium lead perovskite, and the change in X-ray diffraction and Xray photoelectron spectroscopy was discussed.
Abstract: Silver is a low-cost candidate electrode material for perovskite solar cells. However, in such cells the silver electrodes turn yellow within days of device fabrication. The color change is also accompanied by a dramatic decrease in the power conversion efficiency when compared to otherwise identical devices using gold electrodes. Here, it is shown that the color change results from silver oxidation to silver iodide, due to a reaction with iodine in methyl ammonium lead perovskite. The change in X-ray diffraction and X-ray photoelectron spectroscopy is discussed. Exposure to air accelerates corrosion of the Ag electrodes when compared to dry nitrogen gas exposure. However, iodine not reacted with silver is observed by X-ray photoelectron spectroscopy even for the perovskite solar cell kept in dry nitrogen gas. It is proposed that silver iodide is formed when methyl ammonium iodide migration is facilitated by the small pinholes in the hole transport layer spiro-MeOTAD.

TL;DR: A silver iodide smoke generator has been constructed in this paper, which consumes 1 mg of SilverIodide per second and produces 1013 effective nuclei per second, and the maximum temperature at which the SilverIid particles serve as nuclei is approximately −4°C for particles one micron in diameter, and −8°c for particles 100 Angstrom units in diameter.
Abstract: Silver iodide particles have been found to serve as nuclei for the formation of ice crystals in super‐cooled water and in water vapor super‐saturated with respect to ice. It is believed that silver iodide serves as a very effective nucleus because it very closely resembles ice in crystal structure. Both dimensions of the unit cell of ice and silver iodide are the same to within approximately one percent. The maximum temperature at which the silver iodide particles serve as nuclei is approximately −4°C for particles one micron in diameter, and −8°C for particles 100 Angstrom units in diameter. A silver iodide smoke generator has been constructed which consumes 1 mg of silver iodide per second and produces 1013 effective nuclei per second.

TL;DR: The as-prepared AgI/C3N 4 nanocomposites photocatalyst revealed better photocatalytic behavior than the genuine AgI and C3N4 which ascribed to synergic impacts at the interconnection of C3n4 and AgI.

TL;DR: In this article, a macroscopic theory of mixed conduction with special reference to the conduction in silver sulfide group semiconductors is developed with the purpose of identifying the relative electrochemical potential of electrons and ions.
Abstract: A macroscopic theory of mixed conduction–partly electronic and partly ionic conduction–is developed with special reference to the conduction in silver sulfide group semiconductors. Current equations combined with continuity equation give an equation which can be reduced to a diffusion equation under simplifying assumptions. It can be integrated with ease under boundary conditions which are prescribed by the nature of electrodes employed. General expressions for potential distributions arc derived. Two kinds of potentials are distinguished. One is the potential as measured by the use of probes consisting of electronic conductor, and the other as measured by the use of probes consisting of ionic conductor such as silver iodide for silver sulfide. The former reveals the relative electrochemical potential of electrons and the latter that of ions. Calculated time variations of potential distributions for formation and decay processes of stationary polarizations are compared with experiments for Ag 1.93 Te at 1...

TL;DR: The optical changes that occur upon the addition of iodide, iodine, and colloidal silver iodide to a colloidal solution of silver particles (6-nm mean diameter) were monitored spectrophotometrically as mentioned in this paper.
Abstract: The optical changes that occur upon the addition of iodide, iodine, and colloidal silver iodide to a colloidal solution of silver particles (6-nm mean diameter) were monitored spectrophotometrically. For small concentrations of added I - and I 2 (formation of less than a monolayer of adsorbate), the changes in the shape of the silver plasmon absorption band are practically identical. Silver iodide particles in contact with silver particles affect the plasmon band only slightly. It is concluded that the AgI molecules formed by the surface oxidation of the Ag particles by iodine do not possess the properties of bulk AgI
