1. MAULI GROUP OF INSTITUTION COLLEGE OF ENGINEERING AND TECHNOLOGY, SHEGAON . Department of Electrical Engineering Topic :- “ INFRARED PLASTIC SOLAR CELL ” Presented By:- Mr. Suhas A. Ingle Guided by :- Prof. S. S. Bhuskute

2. Technical Seminar on Infrared plastic solar cell

3. The plastic solar cells uses nanotechnology and contains the first solar cells able to harness the sun's invisible, infrared rays. Plastic solar cells could one day become five more times more efficient that current solar cell technology . Plastic solar cell can turn the suns power into electric energy even on a cloudy day. The working of this type of solar cells is same as that of conventional solar cells but these solar cells are of small size and harness all the rays from sun's radiation. Because of their small size and light weight, they exhibit unusual and interesting properties . INTRODUCTION

4. Division of sunlight Sun Visible Infrared Earth

5. Construction of Infrared Plastic S olar C ell The solar cell created is actually a hybrid, comprised of tiny nanorods dispersed in an organic polymer or plastic. Nanorods are made of cadmium solenoid. This layer of around 200 nanometers thickness is sandwiched between electrodes. The electrodes are coated with aluminum.

6. A layer only 200 nanometers thick is sandwiched between electrodes. Nanorods in the plastic solar cell acts like wires when they absorb light of specific wavelength they generate an electron and electron hole vacancy in the rod that moves around just like an electron. The sunlight passes through the transparent plate and electrode is absorbed by the semiconducting donor and acceptor material in the photoactive layer. When Nanorods absorb light they generate an electron and an electron hole. Electron is collected by aluminum electrode. The hole is transferred to the plastic and conveyed to the electrode , to creating a current. Working of Infrared Plastic Solar Cell

7. Better light collection and concentration employed in the solar cells. In plastic cells Nano rods are closely packed and transfer their electrons more directly to the electrolyte. They also hope to tune the Nano rods to absorb different colors to span the spectrum of sun light. IMPROVEMENTS

8. Radio transceivers on mountain tops, or telephone boxes in the country can often be solar powered. APPLICATIONS Telecommunication systems:

9. Hydrogen powered car: Hydrogen car painted with the film could convert solar energy into electricity to continually recharge the car’s battery

10. Ocean navigation aids : many lighthouses and most buoys are now powered by solar cells. Ocean navigation aids:

11. Infrared Plastic Solar Cells Photo- Volatic CELLS

12. Plastic solar cells are quite a lot useful in the coming future. This is because of the large number of advantages it has got. Some of the major advantages are: They are considered to be  30%  more efficient when compared to conventional solar cells. They are more efficient and more practical in application. Traditional solar cells are bulky panels. This is very compact. Conventional solar cells are only used for large applications with big budgets. But the plastic solar cells are flexible as they can be even sewn into fabric thus having vast applications. Flexible , roller processed solar cells have the potential to turn the sun’s power into a clean, green, consistent source of energy. ADVANTAGES

13. They are very costly. Relatively low life span as compared with PV cell when continuously exposed to sunlight. It requires higher maintenance and constant monitoring. LIMITATIONS

14. Plastic solar cells help in exploiting the infrared radiation. More effective when compared to conventional solar cells. They can even work on cloudy days. Though at present cost is a major drawback, it can be solved in the near future. CONCLUSION

15. I mprove the efficiency of plastic solar cell. I mprove the time span of plastic solar cell for widely use. D ecrease the cost of manufacture of plastic solar cell. Research is on to fabricate thin film InAs / GaAs quantum dot solar cell which have alternatively low cost, light weight flexible using the same layer transfer scheme. FUTURE SCOPE
