Solar cars combine technology typically used in the aerospace,bicycle,alternative energy and automotive industries.The design of a solar vehicle is severely limited by the amount of energy input into the car.Most solar cars have been built for the purpose of solar car races.Exceptions include solar-powered cars and utility vehicles.Solar cars are often fitted with gauges as seen in conventional cars.In order to keep the car running smoothly,the driver must keep an eye on these gauges to spot possible problems.Cars without gauges almost always feature wireless telemetry,which allows the driver's team to monitor the car's energy consumption,solar energy capture and other parameters and free the driver to concentrate on driving.Solar cars depend on PV cells to convert sunlight into electricity.In fact,51% of sunlight actually enters the Earth's atmosphere.Unlike solar thermal energy which converts solar energy to heat for either household purposes,industrial purposes or to be converted to electricity,PV cells directly convert sunlight into electricity.When sunlight (photons) strike PV cells,they excite electrons and allow them to flow,creating an electrical current.PV cells are made of semiconductor materials such as silicon and alloys of indium,gallium and nitrogen.Silicon is the most common material used and has an efficiency rate of 15-20%.About the discussion we’ve had about whether China should devote major efforts to developing car industry,opinions are divided on the question.60% of the students think we should try our best to develop the car industry.On one hand,cars will not only make contributions to Chinese economy,but also provide more jobs for the Chinese.On the other hand,with more cars coming into our life,it will become more comfortable and save our time.However,well goes an old saying,“Every coin has two sides.” Cars will also have a bad effect on our life.Therefore,there are 40% of the students who think we should reduce cars.The more cars we have,the more roads we need.There is no doubt that cars will lead to traffic jam and more accident.Besides,cars produce wasted gas,which will pollute the air.As far as I’m concerned,though we should develop our economy,it is the earth we live on that is more important 对不起,我喜欢英语作文,一不小心写多了
