In1999:Researchers at the university of Sao Paulo, Brazil, has devised a new type of solar car,the speed achieved 100km per hour.
Solar car is a car driven by solar energy .Compared with traditional heat engine-
driven cars,solar car is a true zero emissions.Because of its environmental characteristics,solar car was advocated by many countries, solar car industry is also increasingly robust.
Application status:
So far there are mainly two aspects solar energy application technology in automobile:
1. as a driving force:This solar car is different than the traditional car both in appearance and operation.,and no engine, chassis, drive, transmission components, etc,but consists of panels, storage appliances and motor.
Design and Manufacture
Solar car’s most attractive part is the body,its eye-catching appearance is different region amorous feeling and smooth. Solar car is composed of several principal components.Because there is no unified standard for per a solar car each has its own characteristics.
On the solar car is equipped with intensity like cellular device, as the wings of the iron on the satellite,they are solar panels.
Solar cells have many shapes,round, halfround,quadrate etc. Small silicon in solar
4)High energy conversion, less energy intensive;
Noly need 3-4 square meters of solar battery components can make solar electric vehicles,the thermal efficiency is higher
2. as energy for automotive auxiliary equipment:Because of solar radiation intensity is weak, the photovoltaic panels are expensive and limited to many other reason,so solar hybrid cars appeared.
Solar car’s advantages:
1) Never lack engry;
The sun is a huge energy body，don't worry about run out of energy.
2)No pollution,low noise：
Because there is no fuel solar vehicles does not emit the harmful gas of atmospheric pollution, no internal

Development
In 1978:The first solar car successfully developed in Englan.The speed achieved 13km per hour.
In1982:Mexico developed a three rounds of solar car.T speed up to 40km per hour.
combustion engine,so low noise.
3)Simple structure,easy maintenance;
Because of the solar vehicle structure is simple，in addition to the regular replacement battery,almost don’t need源自daily maintenance.
solar battery
Operating principle:
The sun's rays into electricity is an important way of utilizing solar energy.Install the cell in car, use it to make the sun's rays constantly into electrical energy to make the car run.
cells which mixed in some boron and phosphorus.And install electrode on both sides of the silicon wafer， it can turn light
energy into electrical energy.
