Just came across this in news and thought people here might be interested:
"The new FUSION film, embossed with microstructures that bend sunlight, may be installed like a sticker on panels
already in use, improving by up to 10 percent the amount of sunlight that solar panels
convert into electricity. What it does is another variation of concentrating sun light."
Sounds interesting. No opinions though as I don't know price
or anybody tried it.
