Solar Cells
Photovoltaic cells converts solar energy into electricity.
Solar cells convert light directly into electricity
Solar cells for electricity and solar cells for heating are two very different things, so it doesn't make much sense to convert one into the other.
Developing countries often do not have an extensive electricity supply and grid. Villages may be far from this grid and electricity is thus not available. Solar cells can fill this gap and provide local electricity. Developing countries are also largely close to the tropics where there is an abundance of sun.
Solar cells have stored solar energy that is converted into electrical energy.
No. Solar cells have no moving parts.
