There's lots of people who are pointing out that 1000x better might be misleading, which is certainly true here, but let me be a little more exact and explain things briefly (nb I'm a prof of Materials chemistry and am involved in PV research, although it's not my main focus). Firstly, this research does not give the efficiency which is usually the headline number*. Mainly because most of their measurement aren't using sunlight but a laser. Here they see it does interact with light to give electricity and they show the response is 1000x higher current for their new layered materials versus the unlayered type. However, as others have pointed 1000x a low number isn't great. The highest measured current** is 0.5 mA/cm2 although they actually do proper sunlight measurements (under 1.5 suns, which is a common way to measure this) and get 0.035 mA/cm2. This is something we can compare to commercial solar cells and it's almost exactly 100x lower than a commercial silicon solar cell (35 mA/cm2).

Obviously there's a lot more detail and nuance here I'm skipping over but (i) don't expect this to change the world in the near future and (ii) its a new material approach which is cool scientifically and while the uninformed media is hyping it, the scientists in the paper were perfectly reasonable.

If you have any other questions, I'll try to reply ASAP.

*RE efficiencies normal silicon ones are normally around 15%, good perovskite next-gem ones are a bit above 20%, and there's a hard physical limit of 33% for a perfect single solar cell

**They use uA/cm2 because their numbers are low. I've converted to the more common mA/cm2. These data are in Fig 3c and Fig3d. I'd recommend you have a look yourself as there's no paywall. https://www.science.org/doi/10.1126/sciadv.abe4206

That's the real crime

A real conesouir knows it is actually Adaptation, staring Nicolas Cage, Meryl Streep, and Nicolas Cage again (as his own twin brother)

Was "Kyle" not available?

The first default (player controlled) team in Worms on PSX was called "1 UP", with the 4 worms being Ginger, Smidge, Fluff, and Dodger. My sister used to kill smidge in the first round so often it became a bit of a running joke and I adopted it as a screen name. Unfortunately, so did others in the early Internet days, so I went 1337 Sp33k and tweaked it to sm1dger, which I've kept for what must be 20 years or so

Can't believe how many people went through the same steps. I miss reddit, but post RIF, it was unusable

The money is a means to an end. It would be more efficient to steal the drugs themselves. As a first guess, threaten a doctor to steal the drugs and write out a detailed rota of what to take and when for you. Depending on the means used to coerce, leave the country afterwards. Or just live in a country with socialised healthcare

Sarah Connor Chronicals. Was pretty good throughout but then ramped up to off the walls amazing, just in time to be cancelled on a cliffhanger

It's also possible to use the free version and just deal with ads. If you want lemmy to thrive, then sync is exactly the sort of thing we need (it's the only reason I'm here after the final death of RIF)
