2. Topic
Solar cell

3. Definition
A solar cell is an electrical device
that converts the energy of light
directly into electricity.
It supplies a voltage and a current
to a resistive load (light, battery,
motor).
It is like a battery because it
supplies DC power.

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.
Albert Einstein

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

7. Types of solar cell
• Based on the types of crystal used, solar cells
can be classified as,
1. Monocrystalline silicon cells
2. Polycrystalline silicon cells
3. Amorphous silicon cells

8. Comparison among the three types of
solar cells
Material Efficiency (%)
Monocrystalline silicon cells 14-17
Polycrystalline silicon cells 13-15
Amorphous silicon cells 5-7

15. Advantages
1. It is clean and non-polluting
2. It is a renewable energy
3. Solar cells do not produce noise and they are totally silent.
4. They are long lasting sources of energy which can be used
almost anywhere
5. They have long life time
6. There are no fuel costs or fuel supply problems

16. Disadvantage
1. Solar power can`t be obtained in night time
2. Solar cells (or) solar panels are very expensive
3. Air pollution and whether can affect the production of electricity
4. They need large area of land to produce more efficient power supply
