2. # Solar Cell is an electrical device
that converts the energy of light directly
into electricity using photovoltaic effect.

4. # The photovoltaic effect is a process that
generates voltage in a photovoltaic
cell when it is exposed to sunlight.
# The photovoltaic effect was first discovered by
Edmond Becquerel in 1839 .

6. # Crystalline Silicon (c-Si) obtained from
crushed Quartz.
# Doping materials like Phosphorous
and Boron.

7. The operation of a photovoltaic cell requires three basic
attributes:
# The absorption of light to generate either electron –
hole pairs.
# The separation of Charge -Carriers of opposite types.
# The separate extraction of those carriers to an external
circuit.
Operation of Photovoltaic Cell

8. #In powering space vehicles such as
satellite and telescope.
#In solar powered cars.
#In domestic usage such as solar light
bulbs.
Uses of Solar Cells

9. # Generation of solar energy has tremendous scope
in India.
# The geographical location of the country stands to
its benefit for generating solar energy.
# India is a tropical country and it receives solar
radiation almost throughout the year, which
amounts to 3,000 hours of sunshine.
# This is equal to more than 5,000 trillion kWh.
#Almost, all parts of India receive 4-7 kWh of solar
radiation per sq meter. This is equivalent to 2,300–
3,200 sunshine hours per year.
Future of Solar Energy in India

10. Conclusion
DR.C.V. RAMAN UNIVERSITY, KOTA, BILASPUR (C.G.)
Solar cells based on solar energy is the
cheapest source of energy. It is pollution
free and environment friendly source. It is
neat and clean source of energy. In future it
may be our sources of all kinds of energy.
