A flexible perovskite-silicon tandem solar cell has reached a certified 29.88% power conversion efficiency, placing it among ...

Tiny crystal “seeds” could solve a hidden flaw in perovskite solar cells—unlocking high efficiency at larger scales.

Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) in China have ...

Solar power is getting cheaper and more powerful, but researchers are still working to make the next generation of solar panels reliable enough for large-scale use. A new study reports a promising ...

Many new energy technologies look impressive in the laboratory but never become real products. Solar cells are a clear example. Scientists can achieve record performance under controlled conditions, ...

A collaboration between a team led by RASEI Fellow Mike McGehee at the University of Colorado Boulder and scientists at the National Renewable Energy Laboratory (NREL), just published in the ...

Metal-halide perovskite solar cells are attractive for next-generation photovoltaics due to their low fabrication cost and rapidly rising efficiencies. However, exposure to light and oxygen generates ...

To compete with established photovoltaic technologies, PSCs must demonstrate long operational lifetimes, spanning 20-25 years under real-world conditions to match the lifetimes of silicon PV. However, ...

China has quietly pulled off a feat that solar engineers have chased for years, pushing a new cell design to record efficiency by hiding its most important features beneath the surface. Instead of ...
