TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Components: In the left and right sides of the system, front portion and top portion of system are provided with visor. The visor is inclined at the top, and photovoltaic layer is fixed on inclined surface. The support frame is formed using aluminum alloy or carbon fiber material. Photovoltaic layers are arranged parallel to and bonded to visor. The flexible thin-film battery module is covered with film layer. The film layer is coated with coating layer. The area of photovoltaic layer is 60-80% with respect to total area of visor. The flexible thin film battery module is prepared by depositing transparent conductive thin film on flexible substrate. The transparent conductive thin film is prepared using thin film cell including flexible amorphous silicon thin film solar cell, potassium-copper-indium selenide thin film solar cell, cadmium-telluride thin film solar cell, dye-sensitized cell or organic thin film battery.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The carbon fiber is carbon fiber unidirectional reinforcement plate. Preferred Properties: The carbon fiber has fiber content of 2000 g/m2, density of 100 plus minus 2 mm, tensile strength of 2950 N/mm2, elasticity modulus of 185000 N/mm, thickness of 5-10 mm, and length and width of 400x 500 mm, 500x 500 mm, 500x 600 mm or 1000x 1200 mm. The carbon fiber has resin content of 42%, fiber content of 1050 g/m2 and fiber volume content of more than 65 vol.%. The titanium dioxide is rutile titanium dioxide particles surface-modified by silane coupling agent.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The film-forming additive is dodecanol ester.
