Question

describe describe construction and working principle for conservation of solar energy to electrical energy through photovoltaic cells​

Answer 1

Answer:

Solar PV systems use cells to convert sunlight into electricity. The PV cell consists of one or two layers of a semi conducting material, usually silicon. When light shines on the cell it creates an electric field across the layers causing electricity to flow.

Answer 2

• As we know that the sunlight can be converted into electricity with the help of photovoltaic cells.
• The photovoltaic cells conserve solar energy to electrical energy.
• Photons bombard the upper surface when sunlight shines on the cell.
• Through the cell, photons carry their energy down.
• As we know photons give up their energy to electrons in the p-type layer.
• After that, the electrons use this energy to jump across the barrier into the n-type layer and escape out into the circuit.  flowing around the circuit, the electrons make the lamp light up.
