Introduction Photovoltaics developing alternative Work towards energy autarchy of the cities Clean solar energy fuel for vehicles

How solar cells work? Two different types of semi-conductor layers (sillicon) Two layers together => P-N junction Difference in electrons causes current

Brief history The first solar car was invented 60 years ago In 1981 Tholstrup built a solar powered race car in which he crossed Australia Breakthroughs First solar car through the years

Brief history New cars been developed… World Solar Modern racing solar car Challenge invented by Tholstrup, an australian solar car inventor

Advantages of solar cars NO AIR OR NOSIE POLLUTION The purchaser does not have to purchase USUAL fuel Cheaper and less regular maintenance service than conventional cars (Blue, 2014)

Current problems People are not driving solar cars now because: None commonly available in market Too small Design is not appealing to the consumer Not reliable, fuel problems

Dream cars? Nowadays solar cars Would you buy one like this?

The car solution • 4 seater • 120 km/h top speed • 80 k. W motor (Bosch) • 1000 kg full • 150 km range • 30000 $ 4 m 2 of semi-flexible solar panels 8 h recharging from the sun Grid battery charging: 4 h completely, 20 min for 80% full battery

Comparison Drag coefficient 0. 2 Drag coefficient: 0. 28 Electric motor Petrol motor 80 k. W 115 k. W

The city solution • State’s investment into solar panels near parking lots • Recharging cars from the grid(plug in), for a price Picture 6:

Conclusion These solutions would slowly convince the population to change their way of transport. Change the way of thinking Less consumptionate society
