EEVblog 1575 – TIPA: The World’s Most Efficient Solar Panel – BUSTED

TIPA: The World’s Most Efficient Solar Panel raised £293,000 on Indiegogo and Kickstarter, AND also got a UK government innovation grant for £560,000!
They claim 3 times the power output of regular solar panels by using mirrors to reflect the light back on the solar cells (TIPA: Total Internal Photonic Absorption). They claim 80% of the light that hits a solar panel is reflected!

And when challeged by a solar cell researcher from the University of Freiburg on the claims of 80% reflectance and why they don’t independently test, there is a hirarious word salad response!
