Ottawa Senators interest #mbnov

CBC: Canadian actor Ryan Reynolds confirms interest in buying Ottawa Senators

“I am trying to do that. It’s very expensive.”

Added Reynolds with a laugh: “I need a partner with really deep pockets.”

Forbes magazine valued the Senators at $525 million US in December 2021, about four months before former owner Eugene Melnyk died.

Reynolds would have a very different style as franchise owner I’d guess!

All-perovskite two-terminal tandem solar cell tech with 32.3% efficiency [link]

pv magazine: All-perovskite two-terminal tandem solar cell tech with 32.3% efficiency

Indian scientists have designed a new all-perovskite tandem solar cell configuration that can reportedly achieve higher efficiencies than similar devices built with the same materials. The top perovskite cell has a wide bandgap of 1.75 eV and the bottom perovskite cell has a bandgap of 1.25 eV.

Scientists from the Central University of Jharkhand in India have simulated a new all-perovskite two-terminal tandem solar cell. It reportedly has a 13% higher efficiency than similar devices with the same materials at the research level.

Perovskite has the potential to significantly reduce the cost of panels but to date they have suffered from lower efficiency and poor durability. Tandem cells (perovskite over silicon), though, have achieved better efficiencies than silicon alone.
