Technology and R&D

The Chinese electric vehicle maker said the new batteries can charge from 10% to 70% in 5 minutes and from 10% to 97% in 9 minutes. The company also announced a new generation of its Flash Charging Technology.

In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.

Global solar supply chains face renewed price pressure as weak post-holiday demand in China collides with high polysilicon stockpiles, pushing wafer costs lower and weighing on exporters ahead of policy changes.

Researchers in the U.S. have developed a set of guidelines and protocols to assess the performance of three-terminal (3-T) and four-terminal (4-T) tandem solar cells, including those with subcells made of III–V, CdTe, perovskites or silicon materials.

Austrian researchers analyzed commercial ethylene vinyl acetate–polyolefin–ethylene vinyl acetate (EPE) solar encapsulants and found that products sold under the same label can have significantly different material structures and performance. While EPE offers better moisture barriers and thermal resistance than EVA and is rapidly gaining market share, the study warns that its long-term reliability and behavior vary widely and require deeper investigation.

Researchers reviewed 110 studies on cold thermal energy storage in liquid-air energy storage, finding that cold storage performance has a far greater impact on system efficiency than previously assumed. While phase change materials offer high theoretical efficiency gains, simpler packed-bed sensible heat systems are currently the most mature and cost-effective option, with further experimental validation needed to bridge the gap to large-scale deployment.

The 1 MW testing facility is located in Xuwei New Area, Lianyungang, Jiangsu province. It is designed to generate long-term field data on large-area perovskite modules in coastal conditions.

The research team developed the perovskite solar cell with a spin-coated bilayer tin oxide electron transport layer that boosts charge extraction, achieving a 4.52% efficiency and improved stability.

Researchers in Türkiye have developed a passive anti-soiling coating for PV panels using oleic acid–modified aluminum oxide nanoparticles applied via spray coating. Laboratory and field tests showed the coating reduced dust accumulation and initially boosted daily energy output, though performance declined under prolonged environmental stressors.

The Chinese manufacturer expanded its P Class portfolio with two new shingled-module series for residential and commercial rooftop installations. Both lines feature high-density, multi-busbar shingled cells for improved shade tolerance and long-term reliability with 30-year warranties.
