Then it would be MASSIVELY cost effective!
Sure, if those 90% cells were somewhere around the present price of silicon cells.
What if they cost ten times as much? Back to usefulness only to NASA and such.
But organics are getting better year by year for sure.
Bendable cells would make installs a lot easier too.
I often wondered if it would be worthwhile to make movable cells, imagine cells on both sides of a simple roof, if the roof was oriented East-West where one cell produces before noon max energy and the other max energy after noon, would it be worthwhile for a mechanism to be built that allows the two to swing only up and down so they present a united front facing the sun from sunrise to sunset. Would there be enough extra energy generated to make it worthwhile? Mechanically it would be a much simpler support structure than a full tracking set, just one movement, swiveling around a hinge line near the top of the roof.
It could even be done with tough balloon tech, just pumping up balloons to lift the structure up and releasing air to let them down.
What do you think about that idea?
