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! #/ –Queisser_limit @UClilz8CXhUFBRrdAUenRKWw 00:00 - Another Dodgy Crowd Funder 01:00 - £560,000 UK Government Innovation Grant! 01:42 - Let’s watch the video! 06:22 - How it works 06:58 - We can beat the Shockley Queisser Limit! 09:17 - $2BN valuation! 09:28 - The prototypes 10:15 - How they screwed up 12:06 - Reflective coatings and solar panel efficiency tradeoff 13:26 - Some actual reflection measurements using reflectance spectroscopy 15:18 - There ain’t no free lunch.
