increasing efficiency would be more valuable than increasing transparency
This is nothing new to me. I have known about them for a couple of years now. The problems I saw from the research I did at the time that they were not very efficient. It took about three times the surface area to produce the same amount of power as typical panels. But like most things I learned about solar power, it is not the silver bullet for energy but an alternative for particular remote applications where running a power cord was not feasible.
