Do you mean the UniSolar laminate stuff for example?  Maddeningly about 5cm too long for my flat porch roof or I'd already have gone out and bought some and stuck it down!

But if so, that's not quite what I meant.

Rather, PV designed to let some light through like a partial sunshade.

You can definitely get this (decorative and functional) stuff in rigid glass from several sources, but what I have in mind right now is sticking such a thing, reversibly, onto the inside or outside of, for example, my large glass patio doors that in summer otherwise let in too much light and heat.
