A few micrograms of particulates enough to affect PV power generation
New research from South Korea has shown that even a 10 μg/m3 increase in atmospheric particulate matter can considerably reduce solar power generation and impact revenue of PV system owners.
Groups challenge TVA’s draft resource plan that commits to only 3 GW solar
Critics say the federally owned utility TVA, now at 2% solar, plans more gas units, no solar-plus-storage and no long-term storage, in a resource plan that lacks transparency, with no public hearing planned. They asked TVA’s board to ensure improvements.
Sunrise brief: Gavin Newsom rules that schools and farms cannot use their own solar energy production

The shifting sands of PV module supply
Chinese solar manufacturing capacity faces a downturn that is unlikely to translate into growth in other regions, writes S&P’s Edurne Zoco.
NREL researchers want to use tetracene to make singlet fission solar cells
Tetracene is a polycyclic aromatic hydrocarbon that is commonly used in organic field-effect transistors (OFETs), organic light-emitting diodes (OLEDs), or as a sensitizer in chemoluminescence. Singlet fission solar cells can produce two electrons from one photon, making the cell more efficient.
How will PV’s intellectual-property scuffles shake out?
Lawyers are doing brisk business as tunnel oxide passivated contact (TOPCon) solar technology moves into the mainstream. A series of patent infringement cases have been launched in the United States and Europe and their impacts are reverberating through the marketplace. How likely is it that winners will emerge?
