Abstract

Pada penelitian ini telah dilakukan pendekatan untuk meningkatkan unjuk kerja sel surya polimer P3HT:PCBM dengan melakukan kontrol terhadap morfologi melalui annealing lapisan aktif. Proses annealing terhadap lapisan aktif sebagai kontrol morfologi diduga mempengaruhi unjuk kerja sel surya polimer karena akan memperbaiki homogenitas dari lapisan aktif polimer. Sel surya dibuat dengan menggunakan bahan polimer sebagai lapisan aktif semikonduktor organik. Polimer yang digunakan adalah poly(3-heksiltiofen) atau P3HT yang berfungsi sebagai donor elektron, dan [6,6]-fenil C61 asam butirat metil ester atau PCBM sebagai akseptor elektron. Kedua material dibuat dalam struktur bulk-heterojunction film tipis menggunakan teknik spin coating. Dalam penelitian ini, annealing telah dilakukan dengan variasi suhu 120 °C dan 150 °C. Hasil SEM menunjukan bahwa kenaikan suhu annealing mempengaruhi struktur morfologi sampel dimana permukaan lapisan aktif menjadi lebih halus dan homogen. Disamping itu transmitansi minimum kedua sampel terjadi pada rentang panjang gelombang 450-700 nm , dimana sampel 150 °C memiliki transmitansi yang lebih rendah dibandingkan sampel 120 °C. Sebagai hasil karakterisasi listrik, diperoleh nilai parameter untuk sampel 120 °C  dan 150 °C dimana daya maksimum, fill faktor, dan efisiensi, masing-masing adalah, 8,66 x 10-5 W dan 9,39 x 10-5 W, 0,301 dan 0,342, dan 0,028 % dan 0,003 %.Kata kunci: Sel surya polimer, lapisan aktif, P3HT:PCBM, annealing, bulk-heterojunction. The Influence of Annealing Temperature of The Polymer Active Layer P3HT:PCBM to The Performance of Polymer Solar Cells on Glass SubstratesIn this work, the approach has been taken to improve the performance of polymer solar cells based on P3HT:PCBM with controlling the morphology through annealing. Annealing proccess as the control of the morphology is thought to affect the performance of polymer solar cells because it will improve the homogenity of the active layer of polymer. Solar cell is made using the polymer materials as the active layer of organic semiconductor. The polymer that it used is a poly(3-hexylthiophene) or P3HT which serves as an electron donor, and [6,6]-phenyl-c61-butyric acid methyl ester or PCBM as an electron acceptor. Both materials are made in bulk heterojunction structure of thin film technology using spin coating techique. In this work, annealing of active layer has been done with variation temperatures 120 °C and 150 °C. SEM results showed that the increase of annealing temperature affects the morphology surface structure of the sample whre the active layer becomes more smooth and homogeneous. Despitefully, the minimum transmittance of both samples occur over a range of wavelengths 450-700 nm, where the sample 150 °C has a lower transmitance than the sample120 °C. As a result of electric characterization, it is gotten the parameter values obtained for the sample 120 °C and 150 °C, and where the maximum power, fill factor, and efficiency, each of them are 8,66 x 10-5 W and 9,39 x 10-5 W, 0,301and 0,342, and 0,028 % and 0,003 %.Keywords: Polymer Solar Cells, An active layer, P3HT:PCBM, annealing, bulk-heterojunction.

Abstract

In the present work, we used blends of MDMO -PPV [poly(2-methoxy-5-(3,7-dimethyloctyloxy)-1,4-phenylene vinylene)] together with the soluble fullerene C60 derivative PCBM [6,6 phenyl C61-butyric acid methyl ester] as an active layer for bulk heterojunction solar cells. Here, we used a spin coating to deposit a thin and smooth active layer from chlorobenzene solution. An 100 nm thick film of a water solution poly(ethylene dioxythiophene) doped with polystyrene sulphonic acid (PEDOT:PSS) was first spin coated onto an indium tin oxide (ITO)/glass substrate. The PEDOT:PSS layer was then dried in a vacuum oven for 60 minutes at 120C. The active layer, consisting of a blend of the MDMO-PPV and PCBM was then deposited onto the PEDOT:PSS layer from a chlorobenzene solution using spin coating technique. For the cathode, an 134 nm thin film of aluminum was resulted from a thermal evaporation process onto the active layer through a shadow mask to define an active device area of 2,6 cm2. For characterization, the devices was illuminated by a xenon lamp at the intensity of 27 mW/cm2. The temperature ofthe device during characterization was approximately 25C. The device gave an open-circuit voltage of 0.979 volt, a short-circuit current of 0.059 mA, a fill factor of 0.730, and a power conversion efficiency of 0.06%.

Abstract

The aim of this research is to study dye-sensitized solar cells (DSSC). This was implemented on a flexible polyethylene terephthalate (PET) substrate using a mixture of transparent and scattered mesoporous anatase-titania as the electron transport layer for the photoelectrode. This mixture of anatase titania performed a dual function of light scattering and efficient dye absorption. In this study, a porous nano-TiO2 film was prepared on indium tin oxide (ITO) coated polyethylene terephthalate (PET) by using a binder-free titania paste; on it, a DSSC was fabricated. The paste which contained a mixture of TiO2 nanoparticles, acid chloride, and ethanol was printed on two patterns of 1x6 cm2 active areas followed by sintered at 120 ºC to form TiO2 films. A commercial dye, N719, was adsorbed on the surface of TiO2 films and assembled to two platinized conductive plastic patterns to form a counter electrode and thus a sandwich-type dye cell. Finally, a solution of KI/I2 electrolytes was injected into the cell in which a couple of sandwich-type dye cells with an active area of 6 cm2 for each cell were series interconnected with a z-type interconnection between the photoelectrode of one cell and the counter electrode of another cell. The cell performance was characterized by employing simulated solar light at an intensity of 50 mW/cm2. The results showed interconnected cells generating a short-circuit photocurrent density of 2.34 mA/cm2, an open-circuit voltage of 1.10 volt, and overall 0.172% power conversion efficiency.
