Conductivity Of Thin Films

The main focus in this work is to study the electrical properties and efficiency of the mixtureof organic materials that can absorb wide range of light spectrum. Polythiophene (PT) as the main active ingredient acts as a acceptor that absorb light in range 200 -350 nm, while the tris (8-hidroxyquinoline aluminum)(Alq3)and chlorophyll acts as a donor that can absorb light from 350 nm to 700 nm. The combination of PT:Alq3:Chlo is called as bulk heterojunction in organic solar cell.The thin film of the mixture was deposited by using spin coating technique. The energy gap and electrical conductivity of thin films were measured by UV-VIS and 4-point probe respectively. The efficiency of thin film solar cell was determined by 2-point probe. Result of energy band gap of PT:Alq3:Chlo thin film is about 3.72+ 0.02 eV. The electrical conductivity showed increase with the increasing of light intensity. The conductivity of PT:Alq3:Chlo thin film at ratio 3:1:2 under radiation of 100Wm-2 is about 0.250+ 0.001 Scm-1 andthe power conversion efficiency is ~7.16%.

This work focused on the electrical and Hall Effect of Organic Solar cell (OSC). In this work, Indium Tin oxide (ITO) glass as substrate was heated at 50 °C to 200 °C. The polymer used was Poly (3-Dodecylthiophene) (P3DT) thin film and Downy Rose Myrtle berries (RhodomyrtusTomentosa(Ait.) Hassk.) as dye. The P3DT were deposited on the ITO substrate using electrochemistry method at room temperature. While, the dye of Downy Rose Myrtle berries was deposited by layered using spin coating method. The electrical conductivity of ITO deposited thin film was explored by four point probes (FPP) under dark and under light radiation (range of 10 Wm-2 to 200Wm-2). From FPP study, the electrical conductivity was increased by the increment of light intensity and temperature of substrate. Lastly, the samples were examined using Hall Effect measurement to obtain the type of sample, Hall mobility, and highest charge carrier in the sample of OSC. The results show that the sample is suitable for further solar cell application.

Distributed Bragg Reflector

Modification of a cell’s architecture can enhance the performance parameters. This paper reports on the numerical modeling of a thin-film organic solar cell (OSC) featuring distributed Bragg reflector (DBR) pairs. The utilization of DBR pairs via the proposed method was found to be beneficial in terms of increasing the performance parameters. The extracted results showed that using DBR pairs helps capture the reflected light back into the active region by improving the photovoltaic parameters as compared to the structure without DBR pairs. Moreover, implementing three DBR pairs resulted in the best enhancement gain of 1.076% in power conversion efficiency. The measured results under a global AM of 1.5G were as follows: open circuit voltage (Voc) = 0.839 V; short circuit current density (Jsc) = 10.98 mA/cm2; fill factor (FF) = 78.39%; efficiency (η) = 11.02%. In addition, a thermal stability analysis of the proposed design was performed and we observed that high temperature resulted in a decrease in η from 11.02 to 10.70%. Our demonstrated design may provide a pathway for the practical application of OSCs.
