Fraunhofer ISE unveils rotary printing technique for heterojunction solar cell metallization

Researchers at the German research institute have found that indirect gravure printing for metallization of silicon heterojunction solar cells reduces silver consumption and cycle times to below 0. 5 seconds per cell, while still enabling conversion efficiencies of up to 20. 7%. 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, reducing silver consumption at cycle times of 0. 5 seconds per cell, and achieving conversion efficiencies of up to 20. 7%. ...
