Scientists around the world are doing their best to
ensure that they will work differently too.Other options include replacing a car's sunroof with
a panel which has organic solar cells within it. ThisThese
are electric cars, which use electric energy stored
in rechargeable batteries, or hybrids, which use a
combination of petrol or diesel with an electric motor.Cars which
use more sustainable energy are gradually replacing
traditional petrol or diesel powered cars.The car has
photovoltaic (PV) cells in solar panels, which are
made of silicon.These convert the sun's energy into
electrical energy.
