80% Efficient Solar Panel?! Works at Night?

The most expensive, carefully designed, and complicated solar panels in the world operate at about 40% efficiency. That means that, for every bit of sunlight that hits the panel, only 40% of it is turned into electricity.

Scientists think that this is just about as good as silicon panels can do and are now looking at ways to make it cheaper, instead of making them more efficient. But suddenly, from nowhere, comes Steven Novack of the Idaho National Laboratories with an inexpensive, foldable solar panel that may turn out to be up to 80% efficient.
