MIT scientists developing silicon solar cell based on singlet exciton fission
Scientists in the United States have designed a microwire solar cell that could reportedly enable the coupling of singlet fission with silicon. Key to their achievement was an interface that transfers the electrons and holes sequentially into silicon instead of both at once.
Electricity generation from U.S. solar grows 28% year-over-year
Utility-scale solar generation grew to 232 TWh in the rolling 12 months through March 2025, according to the latest data from the Energy Information Administration.
Illinois considers clean energy package to tackle data center boom
Illinois lawmakers are working on an omnibus clean energy package that would introduce a Storage for All program, a Solar Bill of Rights, virtual power plant programs, to name a few.
Letter warns “significant quantities” of solar products could skip U.S. antidumping tariffs
A letter from the American Alliance for Solar Manufacturing said the U.S. Trade Commission must act quickly to ensure tariff rulings are in place before a temporary gap creates an opportunity for solar components to be imported duty-free.
Commercial rooftop solar developer secures $175 million financing
Solar Landscape secured funds from PGIM Private Capital to support its growing project portfolio in Maryland and Illinois.
Solar and battery output records set as California continues aggressive ramp
Amidst industry turmoil, California set a new spring peak for utility-scale solar generation above 21 GW. Battery output exceeded 10 GW as the state surpasses 15 GW of installed energy storage capacity.
Texas to require recycling of retired solar, wind projects
One of the biggest states for solar passed legislation to require the recycling of retired solar and wind projects, pending the governor’s approval.
U.S. defense research agency achieves optical power beaming record
The Defense Advanced Research Projects Agency said a project team testing new optical wireless energy receiver technology was able to transfer 800 W of power to a receiver 8.6 km away in a 30 second transmission. It claims is a distance and power record amongst optical power beaming demonstration results.
All solar cell efficiencies at a glance – updated
The research group led by Professor Martin Green has published Version 66 of the solar cell efficiency tables. There are 17 new results reported in the new version.
Water isn’t always the best answer to BESS fires
Fire protection engineers urge a defensive approach to battery fires, focusing on preventing thermal runaway from spreading rather than putting flames out directly.
