U.S. scientists build antimony sulfide solar cell with 7.69% efficiency
Researchers at University of Toledo produced antimony sulfide (Sb2S3) thin film solar cells with 7.69% power conversion efficiency after determining optimal hydrothermal deposition, post annealing, and light soaking conditions. Stability tests showed more than 95% of initial efficiency after ten months.
How agrivoltaics could solve Nevada’s groundwater crisis
Installing agrivoltaics on previously irrigated land could help minimize the losses from reducing groundwater use, according to a new study published in the Journal of the American Water Resources Association.
Solar power curtailment rises in California
Curtailment – or intentional reduction in power production – continues to rise for both solar and wind power in California.
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.
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.
Nuclear has highest investment risk, while solar shows lowest
Nuclear power plants exceed construction budgets by an average of 102.5%, costing $1.56 billion more than planned, according to a study by Boston University’s Institute for Global Sustainability.
Keeping electricity both reliable and affordable while meeting load demand
A new report from ICF suggests that the U.S. can meet its growing electricity demands with an all-of-the-above energy approach while boosting generation using existing infrastructure.
Solar opportunity as datacenter electricity demand expected to triple in five years
LandGate said as of Q1 2025 datacenters in the U.S. use 200 TWh of electricity annually, up from 147 TWh in 2023, and demand is expected to continue to accelerate.
‘Cybersecurity is a real problem, but the Reuters report should be taken with a grain of salt’
pv magazine spoke with Garikoitz Sarriegi, senior project manager at Kiwa PI Berlin Ibérica, about the Reuters report published on Wednesday that devices susceptible to spying and sabotage had been found in inverters and batteries from China.
