I want to cover the roof of my car with solar cells to power air blower fan to keep inside cabin cool and for possibly other uses too. The usable area is about 1.5 square meters. The surface is painted black and gets up to 180 degrees F in the summer. So far l looked at thin film, but I want something with better efficiency. Is there a solar cell out there that has similar efficiency of polycrystalline stuff, but flexible enough to follow the curvature of my car's roof?
