In this work, Indium Tin oxide (ITO) glass used was 27˚C to 200˚C as substrate. The polymer used was Poly (3-Dodecylthiophene) (P3DT) thin film, Ixora coccinea L dan Rhodomyrtus tomentosa (Aiton) Hassk. as natural dye. The P3DT films were prepared using electrochemistry method at room temperature. Then, the natural dye was prepared layer by layer via spin coating method. Influence of heat treatment on the electrical properties and the efficiency of the system were investigated by Four Point Probes (FPP) under different light radiation (range of 0 Wm-2 to 200Wm-2), Hall Effect and thicknesss measurement. The electrical conductivity of the solar cell system increased with the increment of light radiations and the temperature of substrates. From Hall Effect measurement, the type of sample, Hall mobility, and highest charge carrier in the sample obtained. The thin film thickness was determined. The results show that the sample is suitable for further solar cell fabrications.

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.

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%.

Photovoltaic performance of bulk heterojunction organic solar cell based on poly (3-hexylthiophene) (P3HT) and [6,6]-phenyl C61-butyric acid methyl ester (PCBM) were investigated. The active layer is a spin coated organic blend of a p material (P3HT) and an n-material from the fullerene derivative PCBM; it is sandwiched between electrodes ITO-PEDOT/PSS and Al/LiF as back-contact. Modeling of organic bulk heterojunction solar cells is complicated because of various internal mechanisms involved. Two models have been suggested, namely an effective medium model and a network model. We applied an effective medium model where the main assumption is the p–n nanostructure is treated as one single effective semiconductor layer, and parameters in this configuration are fed into a standard solar cell device simulator, called SCAPS. In this model, other non-carrier related properties, such as the refractive index n, the dielectric constant ε and the absorption constant α are influenced by both p–n materials and used as input parameters. The power conversion efficiency of 3.88% with short circuit current density of 20.61 mA/cm2, open circuit voltage of 0.39 V and fill factor of 48% were obtained. Finally, factors which could limit cell conversion efficiency are discussed.
