  • Silicon is hardly the best path forward but we have seen evidence of international sabotage of progress

    https://pv-magazine-usa.com/2020/02/03/hanergy-named-in-class-action-complaint-by-ex-employees-at-alta-devices/

    Alta had custom implementation of 3-5 growth in order to produce high efficiency solar cells at a price competitive for ships, drones, etc. But once the tech for GaAs becomes competitive with silicon then the industry shifts, that's not a welcomed change.

    Just an opinion.

  • This right here is why you do not ever trust Media coverage of science. This shows a good increase for a particular material system, but to be clear: Silicon solar panels can achieve around 20-25 mA/cm^2 at 0.7 V while this system jumped up to 11.3 MICRO amps at 7 MILLI volts. A jump for a material system is published to show that a material could use further study, but that doesn't mean it's competitive with current tech yet. The real thing to watch for is increasing efficiency and low cost of halides.

    I'm a solar researcher, I'm used to any attention over hyping our results.
