Perovskite solar cells, as a kind of energy conversion device with high efficient photoelectric conversion performance, are considered as a potential solution to the application of car body, aiming to provide auxiliary power for vehicles by directly utilizing solar energy, thereby reducing the consumption of fossil fuels and greenhouse gas emissions.

[0003] However, the current perovskite solar cell technology applied to the car body has a significant limitation, that is, it is usually prepared and installed with a rigid substrate. The design of this rigid substrate limits the effective use of solar cells in non-planar areas of the car body, such as curved surfaces, corners, etc., resulting in limited solar energy collection area, which in turn affects the overall energy conversion efficiency and the self-sufficiency of the vehicle.

[0004] A solar cell for a car is disclosed in a Chinese patent with patent publication number CN102420054A, which includes a photovoltaic cell panel fixed to the top of the car or the top of the car's trunk. The electrical energy generated by the photovoltaic cell panel is used to power the car's headlights, air conditioner and other electrical equipment on the car. The photovoltaic cell panel in this technical solution is a rigid structure, which has poor adaptability to non-planar areas on the surface of the car, and the installation position is limited to the surface of the car's trunk or the top of the car, which is limited in installation position and needs to be improved.

[0008] Furthermore, it also includes a protective film located on the front side of the flexible perovskite solar cell module.

[0009] Furthermore, it also includes an adhesive layer located on the reverse side of the flexible perovskite solar cell module.
