Through the 30% barrier - twice! Our tandem team together with colleagues @CSEMInfo in Neuchâtel have developed two highly efficient perovskite/silicon tandem solar cells with 30.9% and 31.3%, respectively, independently certified @NREL. Read more: bit.ly/3yMKFuc

@a_ginderella Hi, where did you get the information? I've been looking online and couldn't find any confirmation from Paulaner or even where to book tickets

We demonstrated for the first time perovskite/silicon tandem cells based on PERC/POLO Si. It’s intended as a drop-in upgrade to industrial PERC. The proof-of-concept PCE is 21.3% and we estimate a PCE potential of 29.5% onlinelibrary.wiley.com/doi/abs/10.100… @HZBde @UniHannover @eecs_tu_berlin

Happy to announce that our work on understaning interfacial recombination is online for all to read in Advanced Energy Materials! Done with @Stolterlab and many other awesome colllaborators :) onlinelibrary.wiley.com/doi/10.1002/ae…

@chickenzee @professor_dave Sure the government matters, what do you think about my Germany comment? I think you'll find that from country to country its the policy that makes the difference. i. e. Brazil with bad policy lots of cases and deaths. Framing it around own sacrifices is selfish. We all made them

Imagine being a young person, who has put their life on hold for a year to protect the older generation, only to then be told, ah screw it, most of the over 40s are vaccinated now, so you lot can just go out and catch it.

@chickenzee @professor_dave Delta variant comes from neither the UK nor the US. I get that you're angry but why not get angry at the people that caused the issue i.e the government. Look at other countries with similar aged populations in Europe like Germany - sensible policy and the incidence rate is v low

@chickenzee @professor_dave 90% + of cases are delta variant which didn't even exist last summer... Reason for this situation is poor government policy

Great work by Jonas on the pathway to 30% #perovskite solar cells. Oh my God that took forever but it is finally out! Congratulations to Jonas for being so persistent. @Stolterlab @neher_labs @KirchartzThomas @LabUnold @brunoehrler @deibel onlinelibrary.wiley.com/doi/10.1002/so…

@BenKrasnow Hey Ben, I left you a private message about making thin film LEDs and solar cells. Please get in touch if you're interested!

@BenKrasnow Alumina coated boats are the way forward! I use the half inch dimple ones, gives a nice stable rate until failure lesker.com/newweb/evapora…

Unknown gold-looking crystals formed from aluminum and titanium (and oxides or nitrides)....I'll let you know if it turns out to be actual gold. The metal boat is tungsten -- not sure why there is a region of normal looking aluminum crystals.

Back in Belgium after his crash at Il Lombardia, @EvenepoelRemco had a message from the hospital for all those who sent him good vibes in the last couple of days. #TheWolfpackNeverGivesUp

@SnaithGroup work on #perovskite #solarcells degradation and longevity out in @ScienceMagazine , thanks to collabs @durrant_group @LabramGroup @HZBde @UniofOxford @OxfordPhysics @TIFRScience @OxfordMaterials & @EPSRC for funding & @KitaK001 for inspiration science.sciencemag.org/content/369/64…

Looks like some good weekend reads on batteries!

Stability of #perovskite LEDs bit.ly/PvsktSt @acsnano from Henry Snaith @SnaithGroup @UniofOxford /PSW @PSWnano #nano #energy #materials

Happy to announce that our work on what factors influence stability in perovskite LEDs has been published in @acsnano ! Check it out here: pubs.acs.org/doi/full/10.10…

Good luck at @NREL @SevNHabis you will be missed #SnaithlingForLife
