Selenium solar cell with 5.2% efficiency, 0.99 V open-circuit voltage
Danish researchers have built a selenium solar cell with the highest open-circuit voltage ever reported. They said that with further improvements in the optoelectronic quality of selenium, the device could reach an efficiency of up to 8%.
Cadmium sulfide, a poor partner for selenium tandem solar cells
A Danish-German research team has shown that using cadmium sulfide as an n-type partner in heterojunction tandem solar cells based on selenium does not produce satisfying results. The team has discouraged other scientists from following the same path.
Semitransparent selenium solar cell for applications in tandem devices
The bifacial device showed a power conversion efficiency of 5.2% on the front side through an n-type contact and 2.7% on the rear side through a p-type contact.
The raw materials needed for the European Green Deal
A team tasked by the European Commission with estimating the raw material requirements of the European energy transition found if global PV roll-out is high, and the component requirements of certain solar technologies don’t improve by a greater margin, some elements could end up in short supply.
Australian researchers enhance clean hydrogen electrolysis
Griffith University scientists have unlocked a catalytic process to enhance the breakdown of water into hydrogen and oxygen and bring Australia a step nearer clean, efficient hydrogen fuel.
