LONGi Inexperienced Vitality Know-how Co. Ltd. says it has set a brand new world file of 33.9% for the effectivity of crystalline silicon-perovskite tandem photo voltaic cells. The Nationwide Renewable Vitality Laboratory (NREL) licensed the outcomes.
It’s reported that the earlier world file was 33.7% and carried out by King Abdullah College of Science & Know-how (KAUST) in Could this yr.
The brand new file effectivity of 33.9% has surpassed the Shockley-Quieser (S-Q) theoretical effectivity restrict of 33.7% of single junction photo voltaic cells for the primary time. This offers significant empirical knowledge to display the benefits of crystalline silicon-perovskite tandem photo voltaic cells over crystalline silicon single junction photo voltaic cells by way of effectivity.
LONGi says the brand new world file is the primary time {that a} Chinese language firm has achieved the feat for the reason that effectivity file of crystalline silicon-perovskite tandem photo voltaic cells started being tracked in 2015.
