Question

How does a solar panel use the suns rays to create electricity?

Solution

Hi Anvay!

The working principle of solar cell (solar panel) is the photovoltaic effect. When light of sufficient frequency fall on the cell, electron- hole pairs are generated. These electron-hole pairs are separated to their majority regions, due to the electric field of the depletion region. These carriers are collected by the contact terminals, giving rise to the photovoltage.
Cheers!!

Q. While driving in the countryside, Kapil sees some panels attached on the street lights along the road. He finds out that these were photovoltaic solar panels which trap solar energy and converted it to electrical energy to make the streetlights function. He liked this idea so much that he got similar solar panels and installed at his residence also.
Answer the following questions based on the above information:
a). In what respects is the installation of solar panels useful to Kapil?
b). Which values is Kapil promoting by installing solar panels?

c). How can Kapil promote similar values to others in the neighbourhood?
