3. Solar Cell
• A solar cell is an electrical device that converts
the energy of light directly into electricity.
• It product electricity
from sun light.

4. History of Solar Cell
• The photovoltaic effect was first
experimentally demonstrated by French
physicist Edmond Becquerel, In 1839.
• Albert Einstein explained the
underlying mechanism of light
instigated carrier excitation—
the photoelectric effect—in 1905.

5. • The first practical photovoltaic
cell was publicly demonstrated on
April 25, 1954 at Bell Laboratories.
From 2002 we can see the
modern solar cell.

6. Activation
• Photons bombard and penetrate the cell.
• They activate electrons, knocking them loose in
both silicon layers.
• Some electrons in the bottom layer sling-shot to
the top of the cell.
• These electrons flow into metal contacts as
electricity, moving into a circuit throughout a 60-
cell module.
• Electrons flow back into the cell via a solid
contact layer at the bottom, creating a closed
loop or circuit.

8. Uses of Solar Cell
• Solar cell is popular to use
home Power service.
Solar cells are very useful in
powering space vehicles such
as satellites.

9. Uses of Solar Cell
• Solar powered cars, waterbus which are
powered by solar cells.

10. Uses of Solar Cell
• Some modern calculator & cell phone
powered by solar cell.

11. Benefit
• It’s environment-friendly.
• It save our fuel cost.
• It is portable .
• Solar energy is renewable.

12. Future
• In future solar cell & solar power will be see
we in every where.
• We will see solar cell electric Note-book.

13. Conclusion
• Solar cell is very useful, particularly in a time
when we are concerned about greenhouse gas
emissions from other energy sources.
• It will be make our goal decrease our
dependence on fossil fuel
