Thieves steal 50 km of cable from 11 MW solar farm in Germany
Thieves stole 50 km of cable worth about €100,000 ($117,400) from an 11 MW solar project in southern Germany, with repair costs expected to exceed the material loss, according to police.
Copper-metalized heterojunction solar cells close to achieve same efficiency as silver-based counterparts
Researchers in Germany have shown that heterojunction solar cells screen printed with silver-copper on the front side and silver paste on the rear side can achieve a 0.13% efficiency gain over reference screen-printed bifacial cells based on silver alone. The research group worked specifically on dispensing and screen printing as printing methods.
Enpal unveils residential heat pump for large heating loads
