Patent application number: A/00195 - 31 march 2017
Description: The printer is designed for successive deposition of ultra-thin layers with different properties (composition, viscosity, content and nanoparticle size, etc.) and thickness of 0.5 ÷ 2 m. It has modular concept making possible the application of three different deposition techniques, such as: screen printing, doctor blade and wire bar, on the same equipment. Thus, layers of materials with different properties and consistency (viscosity) can be successively deposited. The substrate for printing can also be flexible having a maximum A4 size. This printer has two working areas, one for the ultra-thin film deposition and other for drying / heat treatment (up to 150C).
Application: Although this printer can be used for fabrication of different types of heterostructures it has been designed especially for the manufacture of perovskite solar cells. This type of solar cells requires successive deposition of several ultra-thin layers of different composition and structure.
