i agree with ed. why bend when the cells and reduce surface area. we should just use flat panels attached to sunflowers, they follow the sun all day dont they..

Silicone can easily survive 50 years of direct sunlight, or even more. It can also handle temperature extremes far higher and lower than found anywhere on earth.

Get out your dictionary and look up “convex”.

Presuming it works, and doesnt need to be replaced every few years, it also looks like it’d make an interesting “window tint.”

Plaster a glass skyscraper with it. With some of that mirror-finish glass some buildings use underneath it, light would not only hit the cells first on their way to the glass, but then the glass tint would reflect more light back out towards the back side of the cells, creating a good 20%+ more light hitting the cells.

Old Technology with new lipstick.

The tiny cell is nothing new. It has been around for over 20 years. All they have done is package it up in a silicone resin so light can hit it from multiple directions. Has anyone seen what happens to silicone resin in REAL weather conditions. It kind of loses it’s transparency and gets brittle. So how do you solve the problem? You buy another one to replace it!! Great revenue replenishing product for Kyosemi.

Pay no attention to the man behind the curtain!!! Yea, right.

Dummy…that’s the whole point of the shape…it doesn’t have to be “aimed toward the sun.)

It seems like a concave parabolic array of photovoltaic cells (aimed toward the sun) would be much more efficient. With a convex shape, there will always be a percentage of cells that isn’t directly exposed.
