Longi announces 27.30% efficiency for heterojunction back contact solar cell
The Chinese module manufacturer said the new efficiency record was confirmed by Germany’s Institute for Solar Energy Research (ISFH).
$20 Million federal initiative targets low-emission silicon and thin film research
The Solar Energy Technologies Office has launched a dual initiative to propel upstream advancements in a collection of solar cell types, and to reduce the emissions of solar-grade polysilicon under 1 kg CO2 per kg.
DOE proposes ten “national interest” transmission corridors
Eight of the ten transmission corridors proposed by the U.S. Department of Energy would facilitate transmission between grid regions; one would expand transmission within the Mid-Atlantic’s PJM grid region; and one would expand transmission in the Northern Plains.
Was 2023 the peak for global electricity sector emissions?
A report from Ember highlights how “a new era of falling fossil generation is imminent.”
Powering homes exclusively with hydrogen, solar, batteries
Researchers in Spain has found that combining PV power generation with fuel cells and battery storage may help homes considerably reduce their levelized cost of energy. Their simulation reportedly demonstrated homes may also become completely self-sufficient.
Hotter times will drive rooftop solar value
An analysis suggests rooftop solar will increase in value by between 19% to 25% due to warming and changing weather patterns increasing onsite electricity demand.
NREL interactive chart of solar cell efficiency now including ‘hybrid tandems’
The new cell category includes perovskite/silicon, perovskite/CIGS, III-V/silicon and perovskite/organic tandem PV devices. It will list the absolute record efficiency for all-perovskite, two-terminal tandems regardless of the number of junctions.

Also on the rise: Groups sue FEMA and HUD to focus energy funds on distributed solar and storage. Voltaic releases battery monitoring for off-grid applications. And more.
50 states of grid modernization
North Carolina Clean Energy Technology Center’s recent report looks at how states are doing with legislative and regulatory action related to shoring up the power grid.
Climate change to drive value of rooftop solar
University of Michigan researchers have found that the value of rooftop solar will increase by between 5% and 15% by the mid-century across a range of U.S. cities under moderate climate change, and by up to 20% by the end of the century.
