As a protective measure, cars and set up a barrier between solar panels, silicon, silicon carbide cutting so the actual thickness of the solar panel module is close to 1 cm. This kind of solar panels was originally designed for satellite, thickness of 0. 3 mm, have very strong ductility, can fit the car body. This is a demonstration project sponsored by the Japanese government, Toyota engineers will be sharp, design of the solar panels installed in the prius hood, roof, rear spoiler, and silicon electrode usage of these solar panels generate electricity directly into the car battery driven, when parking the car on the road or directly to recharge the battery. Test shows that, in a sunny day, with the aid of solar charger can make the prius car 56 kilometers, but if there are any cloudy day or the weather is too hot, solar battery charging performance will decline rapidly. The project chief engineer said, reduce the weight of the car, and decrease the cost of its technology is one of the biggest challenges facing at present. Problem in power plant itself also due to the car boot with solar panels, batteries, makes the vehicle's weight increased about 80 kg. Silicon electrode method of use solar wall of CCTV network news: recently, silicon, silicon carbide cutting Japan's Toyota motor company for a test, the satellite using ultrathin solar panels technology, moved to the car in power plant itself problems they want cars don't need to plug in the future, solar energy can drive alone.
