    Po

    Doesn't beat 50% but it should be a lot cheaper.

    A new world record for solar cell efficiency

    That is some really slimy science writing. The nubbin of it is buried in the middle. It says:

    It is through atomic layer deposition that scientists believe they can finally fabricate a working rectenna device.


    So don't go looking for conversion efficiency measurements just yet.

    Is that derived from rectum and antenna?

    It is about as useful.

    Trim I hope that you realize that his work contradicts PJH's claims.

    Solar cells? We are constantly wishin' we
    Could improve by ten times their efficiency.
    My improved solar cell
    Is placed deep down in Hell,
    And its output's increased exponentially.

    No - it is a contraction of rectifier and antenna, and contrary to joshs, it is useful for converting microwave power directly to dc. Of course, you may not find THAT to be useful. It's a matter of taste.

    We've had quite a few "breakthroughs" in the last 10 years years but I struggle to think of any that have made it into production cells?

    It's only useful if you can make it work at an affordable price.

    It's much the same with taste. Gucci and Hermes know this.
