Title : FABRICATION AND CHARACTERIZATION OF ORGANIC AND HYBRID SOLAR CELL

ABSTRACT

This work focused on the study of fabrication and characterization of organic solar and hybrid solar cell. The main objective of this work is to produce organic solar cell device which are better than hybrid solar cell device. Two set of devices, which are bulk heterojuncton (organic solar cell) and ordered heterojunction (hybrid solar cell), have been fabricated with different parameter. For hybrid solar cell, Poly(3-hexylthiophene) (P3HT) was act as a donor while Methanofullerene Phenyl-C61-Butryic-Acid-Methyl-Ester (PCBM) and Zinx oxide (ZnO) nanorod used as an acceptor material. In this experiment, ZnO nanorod was synthesized by irradiation method while P3HT was synthesized by using oxidation polymerization method. Parameters used in this test were PCBM, growth time of ZnO nanorod and power irradiation of ZnO nanorod growth. Highest efficiency of 0.39 % was obtained from power irradiation of ZnO nanorod growth at 550 W, 30 min growth time of ZnO nanorod and addition of PCBM on the film. For organic solar cell P3HT was used as donor and PCBM was acted as charge carrier acceptor. P3HT was synthesized by using same method as in hybrid solar cell for this experiment. Parameters such as Poly(3,4-ethylenedioxythiophene):poly-(styrenesulfonate) (PEDOT:PSS) layer, thermal annealing and ratio of PCBM were used. For organic solar cell, highest efficiency of 2.44 % was obtained from thermal annealing of 140oC, ratio of PCBM (1:4) and addition coating layer of PEDOT:PSS on film. Both devices were characterized by Ultraviolet-visible spectrophotometer (UV-VIS), Nuclear Magnetic Resonance Spectroscopy (NMR), Fourier Transfer Infrared (FTIR), X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscope (FESEM) and Solar Simulator. In conclusion, organic solar cell has higher efficiency than organic solar cell.

ABSTRAK

Kerja ini memberi tumpuan kepada kajian fabrikasi dan pencirian organic solar sel dan hybrid solar sel. Objektif utama kerja ini adalah untuk menghasilkan peranti organik solar sel yang lebih baik daripada peranti hibrid solar sel. Dua jenis peranti, iaitu “ bulk heterojunction” dan “ ordered heterojunction” telah difabrikasi dengan parameter yang berbeza. Bagi hibrid solar sel, Poli(3-hexylthiophene) (P3HT) telah bertindak sebagai penderma manakala Methanofullerene Phenyl-C61-Butryic-Acid-Methyl-Ester (PCBM) dan Zink oksida (ZnO) nanorod digunakan sebagai bahan penerima. Di dalam eksperimen ini, ZnO nanorod telah disintesis melalui kaedah penyinaran gelombang mikro manakala P3HT disintesis dengan kaedah pengoksidaan pempolimeran.Parameter yang digunakan untuk kajian ini ialah, PCBM, masa pertumbuhan ZnO nanorod dan penyinaran kuasa pertumbuhan ZnO nanorod. Kecekapan tertinggi iaitu 0.39 % telah diperolehi daripada ZnO nanorod yang ditumbuhkan pada penyinaran kuasa 550 W, 30 min masa pertumbuhan ZnO nanorod dan penambahan PCBM pada filem. Bagi organic solar sel, P3HT digunakan sebagai penderma dan PCBM bertindak sebagai cas pembawa bahan penerima. Bagi eksperimen ini, P3HT disintesis dengan menggunakan kaedah yang sama dengan hibrid solar sel. Parameter seperti Poli(3,4-ethylenedioxythiophene):poli-(styrenesulfonate) (PEDOT:PSS), pemanasan termal dan nisbah PCBM telah digunakan. Bagi organik solar sel, kecekapan tertinggi adalah 2.44 % teah diperolehi melalui pemanasan termal pada 140oC, nisbah PCBM (1:4) dan penambahan lapisan PEDOT:PSS pada filem. Kedua-dua peranti telah dicirikan dengan menggunakan Ultraviolet Spectrophotometer (UV-VIS), Nuklear Resonan Spectroskopi Magnetik (NMR), Fourier Pemindahan Inframerah (FTIR), Pembelauan X-Ray (XRD), Mikroskop Electron Imbasan Pancaran Medan (FESEM) dan Simulator Solar. Kesimpulannya, organik solar sel mempunyai kecekapan lebih tinggi daripada hibrid solar sel.
