Oxford PV just achieved a new milestone. 25% conversion efficiency makes the perovskite/silicon tandem module the most efficient solar panel. Congrats from our side to Oxford PV and Fraunhofer ISE 🎉

Greetings from the siliconFOREST Workshop (in Germanys Black Forest), where fantastic people present recent advanced in silicon and perovskite solar cells (and various combinations of both) #TandemOnTour

📈 There’s a new category on NREL’s record solar cell efficiency chart!📈 The Hybrid Tandems category captures a range of emerging PV cell designs that combine different absorber materials to yield ever great efficiencies. Peek at the newly updated chart: bit.ly/44tPQO5

Pareidolia! (tendency to perceive familiar patterns, such as faces, in random objects or stimuli) Say hello to our lab buddies! Show us where you see faces in the lab! #LabPareidolia Helmholtz-Zentrum Berlin

For Perovskite/Silicon Tandems, we successfully replaced the ALD-buffer layer with industry-compatible evaporation of BCP. It enables efficiencies of 29.91% for tandems based on @Qcells_EU Q.ANTUM technology Congrats TCO4Pero Marlene Härtel and Bor Li Helmholtz-Zentrum Berlin pubs.acs.org/doi/10.1021/ac…

A long awaited milestone. When i started working on perovskite/ silicon tandems in 2017, the record efficiency was 23.6% on 1cm2(Kevin Bush). Now, only a few years later, modules are sold with even higher efficiencies. oxfordpv.com/news/20-more-p…
