    Do we need more efficient solar panels or just cheaper ones?

    Either or both. Both is better.

    More detail on how the solar-thermal flat-panels work hopefully should be cheaper and efficient.

    Solar power, with a side of hot running water

    Making them more efficient just makes them smaller. Most people can't afford a whole roof full so I reckon making cheaper cells has to be the priority.

    Eventually I expect all houses will be covered by a cheap solar power cells, any excess power will be turned into hydrogen stored for later user in nano hydrides. Which will power transport as well.

    "To manufacture modern solar cells, you have to do extensive semiconductor processing," Fisher said. "All we would need are lenses to focus the light and a fiber to guide it.


    Good luck getting any serious amount of sunlight into a single mode fibre.

    A decent matte black paint performs something like that. The trick is not capture. It's conversion to a useful form.

    New solar product captures up to 95 percent of light energy
    It's a bunch of crap hype. If you don't have a rectifier for that THz energy, a waveguide is useless.

    Well, not strictly true. You can put your coffee in the far end of the guide and get it warmed up.

    PLOL thinks he can do better by rectifying Johnson noise instead, although it's much more likely that he's rectumfying his Johnson rod up someone else's waveguide.

    How many years has PLOL been trying to figure out how to keep his diodes from getting "disturbed"?

    Now, now joshs - don't be noxious or he will give you cancel via an OBE!

    PLOL has long been experiencing an out of mind experience.

    I heard that it was a reverse ping of death that did the damage initially!

    Unfortunately PLOL was confused and directed the reverse PONG of death at his own skull.

    I expect we will need fossil fuels to become much much more expensive before solar cells are competitive except in certain niche markets.
