ABSTRACT

In this study the novel Dual Liquid Feed Ultrasonic Spray Method for arrangement of P3HT: PCBM Bulk-heterojunction dynamic layer in Organic Solar Cells. The benefits of this approach over the typical single bolster way are talked about. Impact of different process parameters on the auxiliary, electrical and optical properties of the mass heterojunction of P3HT: PCBM has been exhibited. The appropriateness of the dynamic layer for its application in OSC has been contemplated utilizing consistent state photoluminescence spectroscopy. The dual feed ultrasonic spray technique for the deposition of active layer with Chlorobenzene: Chlorobenzene, Dichlorobenzene: Dichlorobenzene and Chlorobenzene: Dichlorobenzene solvents combinations for donor/acceptor material are used in this present research work. In this research work, tip of the ultrasonic nozzle is worked at ultrasonic recurrence i.e. 120 kHz for utilized nozzle ultrasonic recurrence flag is produced utilizing the ultrasonic recurrence generator and completed through the ultrasonic broadband link to the ultrasonic nozzle. For exact arrangement conveyance to the ultrasonic nozzle two liquid pumps are utilized for the arrangements of contributor furthermore, acceptor materials independently. Both the liquid pumps are controlled by independent pump controllers. The pumps are synchronized with each other so arrangement can be splashed with every conceivable blend of On-Off cycles of individual pumps. To store the film at wanted temperature substrate were put on the hot plate. PID temperature controller was utilized for exact control on the substrate temperature. It is observed that the dual liquid feed ultrasonic technique has been effectively established for fabrication of P3HT: PCBM active layer deposition. Keywords: Dual Feed Ultrasonic Spray method, P3HT: PCBM, Bulk-Heterojunction
