Photovoltaic cells

a. work because solar energy striking their surface is converted directly to electrical current.
b. causes an uneven magnetic charge to develop.
c. causes the cells to liquefy as they heat.
d. is collected in the form of photons and sent through attached wires. changes to chemical energy.

d. is collected in the form of photons and sent through attached wires. changes to chemical energy. Explanation:

Photovoltaic cell is also known as solar panels. It works by converting energy from sunlight into electricity. This is done when light hits the solar panel, electrons are release from atoms of semiconductors this electrons are trapped by the electric circuits in form of electricity.

Hence it is the photons of light that is trapped by semiconductors and use to generate electricity. Solar panels are used in various companies, houses, labouratories to generate electricity. It is a renewal source of energy and a cheap source because sunlight is not being paid for and its available.

population. population is the number of people or animals in a particular place. an example of population is over eight million people living in new york city.

here is your answer hope i .

what are the options? add them, then i will be glad to .
