Answer 1

SOLAR CELLS:

a) A solar cell (also called Photovoltaic Cell) is an electrical device which converts light energy to electrical energy. Nowadays, it is used as an alternative source of fuel

b) The semiconductor material which is used for making solar cells is SILICON.

c) The uses of Solar Cells are:

• Useful as an alternative source of energy.

• Used for powering and operating Hubble Space Telescope and other satellites.

• Used for lighting the roads in rural areas where electricity (by wire) haven't reached yet.

Answer 2

Answer:

Solar Cells

Explanation:

Solar cells are typically named after the semiconducting material they are made of.

Aluminum or Copper: The two common conductor materials used in residential and commercial solar installations are copper and aluminum. Copper has a greater conductivity than aluminum, thus it carries more current than aluminum at the same size
