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, ...
