  • For a p-n junction based cell, the theoretical maximum efficiency is about 33%.

    You can game this a bit using tandem cells with layers of varying bandgaps, but even as the number of layers approaches infinity the theoretical maximum only increases to about 68%. They’re also not hugely practical or cheap, obviously, and in practice they barely reach above the regular limit of 33% due to engineering constraints. There are some other ways of trying to get around it, but I don’t know of any that can approach 95% efficiency.

    Worth noting that this is staggeringly high efficiency in comparison to most other energy sources, given that at the end of the day all of them ultimately come from sunlight.










  • Look at your first comment. Would you say the same about any other ethnic/cultural group with low genetic diversity? Do you see why it comes across as eugenicist?

    It’s right to be outraged at this settler for what he’s doing to people in their homes. But when people focus genes and ethnicities rather than the crimes of an individual, they dilute blame away from the individual and drag in people who had nothing to do with it.
