The trade-off between transparency and conductivity in transparent conductors used in optoelectronic devices is a major bottleneck towards higher device performances. Grid deposition on transparent conductive oxides was demonstrated using electrochemical deposition, which has the advantage of a high aspect ratio of 0.45 and the possibility to...

Microcontact printing combined with electroless deposition is a potential low cost technique to make electrical interconnects for opto-electronic devices. Microcontact printed inhibitors locally prevent electroless deposition resulting in a pre-defined pattern of metal tracks. The inhibition of electroless Ni deposition on Pd-seeds and on indium...

We report a novel method to selectively deposit materials from solution into imprinted micro-capillaries. Dewetting of the solvent just outside the capillaries is balanced to evaporation inside the capillaries. In this way conductive u-wires can be self-assembled and self-aligned on flexible substrates opening the route to faster and cheaper...

Various transparent conducting materials are compared based on their transparency versus sheet resistance characteristics. At present, transparent conducting oxides (TCOs) are still superior in performance compared to various recent alternatives and can only be surpassed by the combination of TCOs with a metal grid. Results on modeling and...

Integration of functions in single components is pursued in order to manufacture smaller and smarter polymer micro devices at less cost, through e.g. less assembly steps. It requires integration on both product and production side. This paper addresses the use of molded interconnect device (MID) technology for the integration of electronic...

In many flexible electronic devices transparent conductive oxide (TCO) window layers are used for current collection. The trade-off between the electrical resistance and optical transmission of TCOs results in power losses. Increasing the electrical conductivity by combining metallic grids with TCOs enables reduction of these power losses....

Transparent conductive oxides (TCOs) are widely used in optoelectronic applications and are a vital part in thin film solar cells. However, these materials have some drawback, such as brittleness and a maximum transmittance for a certain sheet resistance. Alternative materials, such as metal foils, nanowires and organic conductors are discussed...

At present, transparent conducting oxides (TCOs) are still superior in performance to most other transparent conductors. Results on opto-electronic modeling and design optimization of TCOs are presented using a monolithically integrated CIGS cell configuration as case. For various cell dimensions and TCO characteristics, the cell output was...

Alternatives to ITO are under heavy investigation. Organic and inorganic transparent conducting materials are compared based on their transparency versus sheet resistance characteristics. Although graphene has advanced recently, TCOs are still superior in performance and can only be surpassed by the combination of transparent materials with a...
