Sunrise brief: World’s first anode-free sodium solid-state battery
Also on the rise: Indiana’s largest solar power plant about to come online.
Organic solar cell gains counterintuitive efficiency boost from entropy
A research team at the University of Kansas found that organic semiconductors known as non-fullerene acceptors demonstrate a high solar cell efficiency due to a reversed heat flow.
Researchers build 16%-efficient mini perovskite solar module resistant to UV light-induced degradation
A U.S. research team has built a 15 cm2 perovskite solar module with improved stability and efficiency thanks to a polymer hole transport layer that reportedly improves the panel stability and efficiency.
World’s first anode-free sodium solid-state battery
Researchers at the Laboratory for Energy Storage and Conversion have created a new sodium battery architecture with stable cycling for several hundred cycles, which could serve as a future direction to enable low-cost, high-energy-density and fast-charging batteries.
In case you missed it: Five big solar stories in the news this week
pv magazine USA spotlights news of the past week including market trends, project updates, policy changes and more.
Time to talk solar curtailment
It’s time to assess curtailment, as rising amounts of excess generation are being wasted in several markets. This can be problematic for the solar industry but Toby Couture and David Jacobs, coordinators of think tank Global Solar PV Brain Trust, argue that curtailment is not always bad.
How to speed interconnection studies
Automation of interconnection study processes is already underway and has room to grow, said executives from Pearl Street Technologies and Nira Energy on an industry panel. Other panelists discussed developing the engineering workforce.
All solar cell efficiencies at a glance – updated
The research group led by Professor Martin Green has published Version 64 of the solar cell efficiency tables. There are 19 new results reported in the new version.
Sunrise brief: Looking to Texas as model of speedy interconnection
Also on the rise: UL Solutions introduces new testing protocol for residential battery storage systems. Trina Solar begins mass production of 430-455 W full-black modules. And more.
Experts consider speedy utility-scale interconnection in Texas going nationwide
Some experts shared data to back up their praise for the “connect and manage” approach used by Texas grid operator ERCOT, while others speaking on an industry panel explained their reservations.
