How to print the perovskite solar cells

August of 2015

We develop the technology of smart manufacturing, like a printer, while layers are deposited of nano-droplets, that allows to achieve the accuracy of the layer thickness of 50 nm and a controlled porosity. The printer no longer blind, and can scan and correct their mistakes, like craftsmen. Applications is the individual manufacturing for flexible, different shaped, textile integrated electronics, solar cells, batteries, bio-inspired membranes We can form a very small droplet size of less than a micrometer and compress their flow, but due to the activation of the surface, they do not stick together. High Definition Camera and sensors scan the surface and digital recognize, and comparing the recognized drawing with the original, you can avoid mistakes
Your computer is inserted into a pattern of future products and materials selected for each layer. The printer cartridges are inserted with the correct materials. The printer attached storage, which will be printed materials. Turn on the scanner and it digitizes its shape. Next on the computer selected location on a digitized workpiece where printing will occur. During printing, the scanner compares the printed object with a pattern and displays percentages. If the discrepancy is strong, then the printer head back and corrects

Applications

The smart materials printer that can scan the printed section and digital recognition. This allows you to correct mistakes and print are not blind. Print technology is also applicable to metals and organic materials allows you to create electronic circuits on any surface, provides high adhesion. Special prepared inks for printer (nanotubes, graphene, transparent conductive oxides, metal nano wires)
Printed customer products- solar cells, membranes, batteries, electronics. We was tested our solution in this applications.
Perovskite solar cells on metal foil with printed transparent conductive layer. Primary cost of 17 % efficiency solar cell is 10 USD. Now we are try print tandem perovskite solar cell.
