A new approach for design of organic electrochromic devices with inter-digitated electrode structure

A study of an electrochromic device based on Ni(OH)2/PVA film with the mesh-like silver counter electrode

“…In case of the latter scenario, another question arises -is there a way to somehow reduce or eliminate color non-uniformity? Considering that such designs are currently not used for electrochromic devices and structural innovations are an important aspect, which is reviewed in the scientific literature [21], investigation of assumed scenarios is necessary.…”

Morphology of Electrophoretically Deposited Films on Electrode Strips

“…26,27 One such experimentally relevant geometry, the planar strip electrode, 13,[28][29][30] seems to have escaped the attention of the modeling community. A key feature of this geometry, which is absent in the geometries studied previously, is the presence of electrode edges which we show locally enhance the electric field and significantly affect the morphology of the deposit.…”

“…Electrophoretic deposition (EPD) is an industrially relevant process 1 in which colloidal particles suspended in a liquid are forced to deposit onto an electrode under an applied electric field. While EPD was originally developed as a process for painting metals, 2,3 it is now recognized as a general method for depositing material on any conductive surfaces and has found diverse applications in areas such as thermal barrier coatings, 4,5 transparent ceramics, 6,7 solar cells, 8,9 fuel cells, 10,11 solid-state lighting and displays, 12,13 and medical implants. 14−18 The first theoretical treatment of the deposition kinetics of EPD was performed by Hamaker 19 who predicted that the mass of the deposited film on an unpatterned planar electrode is proportional to the charge passed at the electrodes.…”

“…While it is evident that considerable work has been done to model the EPD process analytically under various conditions in planar and cylindrical geometries, more complicated geometries have not generally yielded analytical solutions but rather have been studied numerically. , One such experimentally relevant geometry, the planar strip electrode, ,− seems to have escaped the attention of the modeling community. A key feature of this geometry, which is absent in the geometries studied previously, is the presence of electrode edges, which we show locally enhance the electric field and significantly affect the morphology of the deposit.…”
