Randy Atkins: Melissa Grossman, president of Genie Lens Technologies, says solar power can be boosted more than ten-percent by inexpensive micro lenses…either embedded on solar panel glass or applied with a sticker-like film.  It’s not a magnifying glass.

Melissa Grossman: We work by bending and manipulating the light so that more of the light that hits a photovoltaic panel actually stays within the panel and has a greater chance of being absorbed by the underlying absorber technology.

Randy Atkins: The micro lenses change the angle that light comes in so that less is reflected away, and…

Melissa Grossman: …it’s going almost horizontally through that absorber material and gives it a much better opportunity to be absorbed.

Randy Atkins: Internal reflectors also keep the light trapped inside to do its work.  With the National Academy of Engineering, Randy Atkins, WTOP News.

The technology, which actually works best on cloudy days, could be ready in about a year.
