The cell was fabricated using a novel interfacial phase equilibrium strategy that suppressed uncontrollable migration of metal ions. The device achieved an exceptionally high open-circuit voltage of more than 600 mV at a band gap of 1.10 eV. February 27, 2026 Emiliano Bellini The Chinese Academy of Sciences (CAS) has manufactured a kesterite (CZTSSe) solar cell that achieved a world record energy conversion efficiency of 15.45% and a certified efficiency of 15.04%. Kesterite is one of the most promising candidates for a light-absorbing material for potential use in lower-cost thin-film solar cells. Kesterites include common elements such as copper, tin,…

HydrogenPro says its 220 MW ACES Delta project in Utah is nearing completion, with all electrolyzers operating at full load, while the hub will store hydrogen in salt caverns with an energy capacity two to three times greater than that of all U.S. grid-connected batteries combined. February 27, 2026 Sergio Matalucci HydrogenPro said the 220 MW ACES project in Utah, United States, is nearing completion. HydrogenPro is the exclusive supplier of electrolyzers. “This project is one of the world’s largest sustainable hydrogen projects and is expected to have a significant impact on California’s power supply,” said the Norwegian company, adding…

In a new weekly update for pv magazineOPIS, a Dow Jones company, provides a brief overview of the major price trends in the global PV industry. February 27, 2026 OPIS Free-On-Board (FOB) TOPCon cells remained stable this week amid weak trading activity during the Lunar New Year holiday break. According to the OPIS Global Solar Markets Report published on February 24, FOB China TOPCon M10 cell prices were found stable at $0.0559/W this week.

The China Nonferrous Metals Industry Association (CNMIA) says polysilicon production has fallen to 32% of capacity, maintaining oversupply, while wafer prices are weakening as demand fails to recover after Chinese New Year. February 27, 2026 Vincent Shaw The CNMIAChina’s Silicon Industry Division said polysilicon prices continue to decline, with limited transactions and subdued purchases after the Chinese New Year holidays. Business rates among manufacturers fell to 32%, but oversupply remained. Wafer prices also fell, with n-type G10L averaging CNY1.10 ($0.15) per piece, down 8.33%; G12R at CNY 1.20, down 4.76%; and G12 at CNY 1.40, down 3.45%. The trade association…

China is bringing online a 300MW/1,200MWh network-forming energy storage facility in Inner Mongolia, integrating lithium-ion and vanadium flow battery technologies. February 27, 2026 Tristan Rayner By ESS news A 300MW/1,200MWh battery energy storage system (BESS) in Ordos, Inner Mongolia, has been put into commercial operation after completing performance validation testing. The project uses a combination of lithium iron phosphate and vanadium flow batteries, with the aim of combining fast response batteries with longer duration storage in a hybrid configuration. It uses grid-forming energy conversion systems supplied by Sineng Electric, each with a capacity of 1.25 MW. The system can provide…

Unsurprisingly, EnergySage’s solar market saw significantly increased traffic in the second half of 2025, following July’s One Big Beautiful Bill Act (OBBBA), which eliminated residential tax credits on December 31, 2025. EnergySage saw a 205% year-over-year increase in the number of homeowners actively working with installers and a record number of customer inquiries over the previous 30-day record. Most installers reported that they would reach annual capacity by October 2025, creating supply constraints and forcing both installers and homeowners to make atypical decisions. These details and more were revealed on the 22nd “EnergySage Intel: Home Electrification Marketplace Report,” released today.…
