Answer 1

Answer:

Explanation:

Photovoltaic modules, commonly called solar modules, are the key components used to convert sunlight into electricity. ... Light striking the crystals induces the “photovoltaic effect,” which generates electricity. The electricity produced is called direct current (DC) and can be used immediately or stored in a battery.

Answer 2

Answer:

It is also called Photovoltaic cell

PRINCIPAL: A solar cell works on the photovoltaic effect in which an emf is produced between the two layers of a pu-juction as a result of irradiation.

USES : 1) They are very useful in powering space vehicles such as satellites and telescope (e.g . Hubble)

2) They provide a very economical and reliable way of powering objects which would otherwise need expensive and cumbersome fuel sources.
