Solar cells convert the energy of sunlight into electrical energy and generate electricity using two types of semiconductors, P-type semiconductors and N-type semiconductors. When light shines on the solar cell, electrons and holes are generated inside. The generated charges move to the P and N poles, and a potential difference (photovoltaic power) is generated between the P pole and the N pole by this phenomenon. Connecting a load causes current to flow. This is called a photoelectric effect. Solar cells can be roughly divided into those using a silicon semiconductor as a material and a compound semiconductor as a material. In addition, the silicon semiconductor may be classified into a crystal system and an amorphous system (AMOLFASS). Recently, high efficiency solar cells and thin film solar cells with energy conversion efficiency of more than 20% have been developed. Currently, silicon semiconductors are commonly used as photovoltaic power generation systems. In particular, single crystal and polycrystalline solar cells of crystalline silicon semiconductors are widely used because of their high conversion efficiency and high reliability. AMOLFASS solar cells, which are already spreading in clocks and desk calculators, are suitable for mass production and are low in price compared to crystal systems, but have a disadvantage of being inferior to crystal systems in terms of conversion efficiency.

Thin film solar cells manufactured in the form of a thin film include a silicon thin film type and a compound thin film type. Thin-film solar cells have the advantage that they can be easily used where the efficiency is low but the surface is irregular or difficult to install. Particularly, the compound thin film type is a technique of depositing a compound composed of elements of CIGS (copper indium gallium selenium) on a flexible substrate such as glass or metal foil polymer to a thickness of 1 to 2 μm. Such thin-film solar cells can be transported or stored like rolled up cardboard.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings of a vehicle cover set having a thin film solar cell.

According to the design, an embodiment in which the roller case 1200 is installed in the rear bumper of the vehicle may be considered. 2 to 4 and below will be described with an example in which the roller case 1200 is installed in the trunk. The roller case 1200 is preferably provided in parallel with the width direction of the vehicle. The roller case 1200 may be attached and fixed to the frame structure inside the trunk of a vehicle using a magnet, but may be coupled using various fastening structures such as nails and adhesives. The winding roller 1100 may be built in the roller case 1200 to be rotatable. A lead part 1210 may be formed at an outer upper end of the roller case 1200 to serve as a doorway of the cover 1300, the left auxiliary cover 1500, and the right auxiliary cover 1600. A foreign matter removing unit 1211 may be selectively formed in the lead portion 1210 to remove foreign substances on the bottom surface of the cover 1300. However, when the cover 1300 is the solar cell film 1360, since the solar cell film 1360 may be damaged by the foreign matter removing unit 1211, the sun may be formed on the top surface of the cover 1300. When the battery film 1360 is provided, the foreign material removing unit 1211 may be formed only on the bottom surface of the cover 1300. When the cover 1300 is opened or closed or covered in an automobile, if there is foreign matter on the bottom surface of the cover 1300, the surface of the vehicle may be soiled and the surface of the vehicle may be damaged by friction in the opening and closing process.
