China's perovskite solar panels beat silicon in real-world field test
A 1 MW perovskite system outperformed silicon by 3–6% in a three-month industrial trial, solving durability challenges that blocked commercialization.
What to know
- Perovskite solar panels achieved 22% efficiency (meter-scale record) and outperformed silicon by 3–6% daily output in a three-month real-world field trial.
- New coating chemistry using organic lead-carboxylate salts solved two critical manufacturing barriers: no inert atmosphere required, and even coverage of large sheets.
- Durability testing showed the new coating retains 98% efficiency after 1,300 hours in hot, humid conditions and 300 rapid thermal cycles—vs. 39% power loss for standard ammonium coatings.
- Researchers view the stability breakthrough as clearing the final obstacle to commercial-scale perovskite production as a silicon alternative.
“The perovskite array generated 3.42 percent more daily electricity per unit of installed capacity in March, 3.79 percent more in April, and 5.81 percent more in May, widening its lead as spring temperatures rose”
