New Passivation Strategy Boosts Perovskite/Silicon Tandem Solar Cell Performance
Researchers at NIMTE and partner universities introduced a peak‑selective passivation technique that deposits a thin aluminum‑oxide layer on the pyramid peaks of silicon substrates using polystyrene nanospheres. The approach lifted perovskite/silicon tandem cell efficiency to 33.33%, with a certified value of 32.89% on a 1 cm² active area. Operational stability also improved, retaining roughly 90% of its initial performance after 1,000 hours of continuous illumination. The method is simple and compatible with existing manufacturing lines, moving the technology closer to commercial rollout.

The Absence of the ‘Duck Curve’ on Monday 18th May 2026 Stands Out, in Recent History
On Monday 18 May 2026 the Australian National Electricity Market (NEM) saw an unusual flattening of the classic ‘duck curve.’ Cloud cover depressed solar output while wind generation recovered, keeping midday electricity prices elevated instead of the typical low‑price dip. Battery operators...

Dominion and NextEra Weigh a $400 Billion Megamerger
NextEra Energy and Dominion Energy are in advanced talks to merge, creating a utility conglomerate valued at over $400 billion. The combined entity would stretch from Dominion’s Virginia stronghold—home to a dense data‑center ecosystem—to NextEra’s Florida operations serving roughly six million...

Are Data Centres Moving to DC Power?
Data centre operators are revisiting direct‑current (DC) power as a way to trim energy costs for AI‑intensive workloads. By moving the AC‑to‑DC conversion from each server to a larger rack‑level supply, facilities can capture 10‑15% savings on total power budgets....
A Snapshot of the Generation Mix Across the NEM, on Monday Morning 18th May 2026
On Monday morning, 18 May 2026, a snapshot of Australia’s National Electricity Market (NEM) showed a dramatic dip in renewable generation due to extensive cloud cover over southeast Queensland. Solar output was heavily suppressed, and wind generation was also below typical levels,...

Trump’s Tax Law Is Slowing Down Projects and Piling Up Legal Work
The Trump administration’s One Big Beautiful Bill Act introduced foreign‑entity‑of‑concern (FEOC) rules that govern eligibility for clean‑energy tax credits. Because the Treasury has not clarified how to calculate foreign debt or equity exposure, developers, investors, and banks face uncertainty about...

South Carolina County Mulls Lifting Solar Ban
