In this paper, the photoelectric conversion of electric cars is discussed and analyzed, considering the optimization of the area of the body, and the efficiency of the solar panels, a mathematical model is established, which is not considered the economic factor, only considering the solar panels on the surface of a vehicle, but also does not cause too much waste, and maximize the ability to improve the E6. Therefore, first find out the car each area and various solar panels specifications, and then use linear programming to find out ...
