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

A flexible perovskite-silicon tandem solar cell has reached a certified 29.88% power conversion efficiency, placing it among the highest recorded results for this class of device and bringing the ...

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, ...

Laboratory testing has revealed that some negatively-doped, “n-type” tunnel oxide passivated contact (TOPCon) and heterojunction (HJT) solar modules are susceptible to ultraviolet (UV) light-related ...

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 ...

Researchers at The Hong Kong University of Science and Technology (HKUST) have developed a multi-source co-evaporation recipe ...

Inverted perovskite solar cells offer strong potential for scalable, low-cost solar power, but a hidden interface inside the device has limited their performance and durability. Researchers have now ...

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 ...
