INTRODUCTION TO FLEXIBLE ORGANIC SOLAR CELL

THE ACTIVE LAYER IN OGANIC SOLAR CELL

Composed of an electron donor and

electron acceptor

3 types of junctions

1. single layer

2. Bilayer

3. Bulk heterojunction

Usually the excitons from the electron

donor are responsible for the

photocurrent

Indium Tin Oxide

Electron transfer from electron donor to

accepter (e.g., PC60BM)

PHYSICS OF ORGANIC SOLAR CELL

WHY FLEXIBLE SOLAR PANEL?

• A large amount of light can be absorbed with a small amount of organic materials• Cost effective• Formed on plastic, paper• Highly flexible,portable and light weight• Capable of producing voltages exceeding than 50V at normal lighting

conditions.• Uses vapor deposition technique so it is easier to manufacture on

ordinary paper to be flexible.

APPLICATION

• Military • Satelight• Carry Bag

CONCLUSION

Due to highly thin, flexible and light weight ti is portable. Due to large

amount of absorption of light it gives maximum energy. It is cost

effective because it uses paper or thin plastic for base material. It’s

efficiency, physical structure and performance is more better than

conventional solid solar panel.
