3.  Classical photovoltaic solar cells based on
inorganic semiconductors (Silicon) was
developed in 1954 by Chapin, Fuller and
Pearson in the Bell Labs.
•Some of its demerits :
Silicon is expensive.
Not flexible
Limited availability of inorganic material.

4. WHY ORGANIC SOLAR CELLS ?
Ease of Processing
Mechanical flexibility
Economically viable
Safer environment
Unlimited availability
Less expensive than inorganic materials (Si).
Compatibility (thin cells)

5. •Optical photons absorbed and creates
exitons (bound electron-hole pair).
•The negative electrode is Aluminum.
•Indium Tin Oxide(ITO) is the
common transparent electrode.
•The substrate is glass.
•Current is generated when the
resulting free electrons and holes are
transported through the donor
polymer and acceptor fullerene,
respectively, to the electrodes.

 It has only one active layer between cathode
and anode.
The donar and acceptor polymers are merged.
So distance between electron and hole pair is
decreased.

9. • OSCs are easily manufactured.
• Molecules are easier to work with and can be used
with thin film substrates that are 1000 times thinner
than Silicon cells.
• This fact reduce the cost production significantly.

10. ENVIRONMENTAL IMPACT
•Less energy consumption in manufacturing OSC than
the Inorganic solar cells.
•An extensive use of OSC contribute to the increased
use of solar power globally and make renewable energy
sources friendlier.
