Scientists from the Fraunhofer ISE built a bifacial heterojunction solar cell with a power conversion efficiency of 21.7% via rotary screen printing. They used a machine that is able to achieve a ...

Researchers at Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) have used indirect gravure printing for front-side metallization of silicon heterojunction (SHJ) solar cells, ...

Students at ETH Zurich have developed a multi-metal 3D printing process that can produce rocket engine components in days ...

How does a typical printing machine work? Today's most common printing machines use a flexographic process. Flexography is a direct rotary printing method that uses a raised image surface to print on ...

Researchers have, for the first time, used a conventional, high-throughput printing process to create sheets of high-quality carbon nanotube transistors on flexible plastic (PET) sheets. These ...
