The subject of this offer is a new, low-cost and compatible with roll-to-roll technology method of precise fabrication of structures already at the stage of creating thin layers.
Application: production of thin layers for the production of large-scale "plastic" electronics and third generation solar cells.
The subject of the invention is a device and method of creating thin layers by means of a sliding meniscus. Device operation is based on horizontal dipping where a small amount of solution is placed between the bar and the substrate which moves under the bar using a computer-controlled linear stage. In the proposed method current/voltage applied between the conductive substrate and electrode forming on the bar or focused light initiate deposition reaction (electro-palting, photo-plating). This innovative technology enables creating and controlling a structure of thin layers.
Advantages of technology
- Fabrication on a flexible substrate;
- A method compatible with roll-to-roll technology;
- Fast and efficient method;
- Reduction of material costs (performing the reaction in the meniscus does not require immersion of the entire substrate in the solution, but only the application of a small amount of solution between the guide element and the substrate);
- Spatially controlled deposition (printing)
Examples of applications
With the device, obtaining structures/layers from inorganic and organic materials with controlled shape, thickness and/or width on conductive and non-conductive substrates (including elastic substrates) is possible.
These structures are used:
- diode;
- third-generation photovoltaic cell (solar cell prototype avaiable);
- transparent conducting film (prototype of sample);
- printing of metallic paths;
- galvanization (chrome plating, tinning, coppering, nickel-plating, gold plating, etc.).
We offer the opportunity to prepare test samples for your verification.
