The Helmholtz Zentrum Berlin set a world record for perovskite-silicon tandem cell efficiency last year at 29.15%. The group has delved further into the cell materials, looking to better understand mechanisms behind the impressive efficiencies achieved so far. Their latest work shows that with the current cell design, long term stability at efficiencies up to 32.4% should be possible.After a few years of rapidly increasing efficiency records, 2020 has seen research into perovskite solar cells shift towards gaining a fuller understanding of mechanisms behind the impressive performances reported ...Den vollständigen Artikel lesen ...
