I read in a couple of places that researchers at Sheffield University have made spray-on perovskite cells at efficiencies of 11%. I was interested in this because it is lightweight and could fit more unusual shapes. I was also looking into regular perovskite cells which are at a max of 19% and are usually bendy, but I thought this may still be constrained to certain shapes. I might be able to cut it, but I feel like I'd probably sever wires and therefore the current flow. The shape I'd need to fit is more or less an isosceles triangle. I could also make the design sort of pixelated (for lack of a better word), just like how these panels are staggered near the edge (see the picture below) but I don't think that would use the surface area as efficiently.
Thanks in advance for any help!
