TL;DR: Raman microscopy was used to investigate microstructural properties of amorphous MoO3 thin films that had been subjected to a photochromic or electrochromic (EC) process as mentioned in this paper.
Abstract: Raman microscopy was used to investigate microstructural properties of amorphous MoO3 thin films that had been subjected to a photochromic (PC) or electrochromic (EC) process. The Raman spectra cha...

TL;DR: An electrochromic layer-set, operating with hydrogen, comprises a transparent substrate front face plate, at least two electrodes, a hydrogen ion-storing layer, and a rear face in sealing relationship with the layer set, directly following one of the two electrodes.
Abstract: An electrochromic layer-set, operating with hydrogen, comprises a transparent substrate front face plate, at least two electrodes, at least one electrochromic layer, a hydrogen ion-storing layer, a hydrogen ion-conducting layer, a rear face in sealing relationship with the layer-set, directly following one of the two electrodes, there being a metallic layer between the rear face and the layer lying in front of the rear face (the electrode) or the rear face itself is formed by this metallic layer. The side of the metallic layer turned away from the substrate plate is optionally transformed into the oxide of the metal. For the application of such a metallic layer, the layer-set and a counter-electrode are immersed in an electrolyte containing the metal ions, with the electrode lying at the rear face of the layer-set being made the negative electrode.

TL;DR: In this article, the reversibly oxidizable layer (D) comprises a transparent dispersion layer made by vacuum thin film formation techniques or thick-film processes and which comprises a metal iridium, iridium oxide or iridium hydroxide disperse phase (D11) and a transparent solid dispersion medium (D12).
Abstract: An electrochromic device including one electrode layer (A), a cathodically coloring electrochromic layer (B), an ionic conductive layer (C) if required, a reversibly oxidizable layer (D) and another electrode layer (E), at least one of the one electrode layer (A) and the other electrode layer (E) being transparent, and at least one of the cathodically coloring electrochromic layer (B), the ionic conductive layer (C) and the reversibly oxidizable layer (D) being adapted to contain protons or include a proton source for emitting protons upon application of a voltage. The reversibly oxidizable layer (D) comprises a transparent dispersion layer (D1) which is made by vacuum thin film formation techniques or thick-film processes and which comprises a metal iridium, iridium oxide or iridium hydroxide disperse phase (D11) and a transparent solid dispersion medium (D12), or the reversibly oxidizable layer (D) and the other electrode (E) are replaced with a single transparent conductive dispersion material layer (D1a) which is made by vacuum thin film formation techniques or thick-film processes and which comprises a metal iridium, iridium oxide or iridium hydroxide disperse phase (D11) and a transparent conductive solid dispersion medium (D 12a).

TL;DR: In this paper, a sealed insulated glass unit is provided with an electrochromic device for modulating light passing through the unit, which is controlled from outside the unit by a remote control electrically unconnected to the device.
Abstract: A sealed insulated glass unit is provided with an electrochromic device for modulating light passing through the unit. The electrochromic device is controlled from outside the unit by a remote control electrically unconnected to the device. Circuitry within the unit may be magnetically controlled from outside. The electrochromic device is powered by a photovoltaic cells. The photovoltaic cells may be positioned so that at least a part of the light incident on the cell passes through the electrochromic device, providing a form of feedback control. A variable resistance placed in parallel with the electrochromic element is used to control the response of the electrochromic element to changes in output of the photovoltaic cell.

TL;DR: In this paper, the authors proposed a mixture of mixed ionic/electronic conductors for use as electrodes in secondary batteries and electrochromic displays, where charge compensation is achieved by a variation of mobile-electron concentration in the host matrix.
Abstract: Insertion compounds contain a mobile cation of variable concentration over a wide range of solid solution. Charge compensation is achieved by a variation of mobile-electron concentration in the host matrix. Such mixed ionic/electronic conductors are of practical interest as electrodes in secondary batteries and electrochromic displays. Oxides containing transition-metal ions in unusually high valence states can be prepared by room-temperature extraction of mobile cations from such structures. Some properties of the systems Li1-yCoO2 and Na1-yCoO2 are presented.
