- nothercastle 3y agoGreat but only 4% and unclear if the increased efficiency would justify the production cost
- kresimirus 3y agoSounds like something I would write in my yearly performance self-review
- mepiethree 3y agoobviously not going to save the world by itself but 4% improvement in solar efficiency would be equivalent to 10s of millions of tons of CO2 reduction if this turns out to be scalable
- huytersd 3y agoIt’s… 1%. How are you getting 4%?
- anonuser123456 3y agoPercentage increase is 4.16667%
- JohnVideogames 3y agoOne percentage point is a four relative percent increase here: (25/24) = 1.041
- tomas789 3y ago24 * 1.04 = 24.96
- julienfr112 3y agoDo you mean one point ? 25/24=1.04...
- wolverine876 3y ago> obviously not going to save the world by itself Sorry to pick on something said in passing, but nothing saves the world by itself, nothing and nobody. People love to say, 'my vote [or whatever they do] won't change things'. Nobody can change things by themselves, yet things are changed enormously by people - how is that? :)
- heresie-dabord 3y agoFuller context from TFA: > Produced in collaboration with the Fraunhofer Institute for Solar Energy Systems, the panel achieved a record 25% conversion efficiency, a significant increase on the more typical 24% efficiency of commercial modules. > Oxford PV, a spin-out of the University of Oxford, is a world leader in the development of perovskite-on-silicon tandem solar cells, which have a theoretical maximum efficiency of over 43%, compared to less than 30% for silicon solar cells.
- mark-r 3y agoI was wondering that myself, 25% doesn't seem like a "significant increase" over 24%. I'm wondering if it's just sloppy reporting. At the end they claim their record breaker was 28.6%.
