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

Monolithic dye-sensitized solar cells (DSSC) offer the prospect of lower material cost and require a simpler manufacturing process compared with conventional DSSC. Fabricated on a single fluorine tin oxide (FTO) glass substrate consists of a nanoporous TiO2 photoanode layer, a ZrO2 spacer layer, a carbon counter electrode layer, a dye, and an electrolyte. The spacer layer on the monolithic DSSC serves as electrolyte storage and insulating layer to separate between photoanode and counter electrode. Zirconia is often used as a spacer because it has high temperature resistant properties, high dielectric constant and adhesive as an insulator that has band gap between 5-6 eV. The effects of the thermal treatment of zirconia layer as a spacer electrolyte on the performance of monolithic DSSC have been investigated. The cell’s performance increases with the sintering temperature as well as indicated by the decreased in particle size and increased in quantum efficiency in the absorption region of the titania layer. Co-sintering treatment tends to drastically reduce cell’s performance. The highest performance was obtained at a temperature sintering of 500o C with an PCE of 0.22%, Isc = 0.16 mA and Voc = 0.71 V.

Abstract

Hybrid polymer solar cell has privilege than its conventional structure, where it usually has structure of (ITO/PEDOT:PSS/Active Layer/Al). In humid environment the PEDOT:PSS will absorb water and hence can easily etch the ITO. Therefore it is necessary to use an alternative method to avoid this drawback and obtain more stable polymer solar cells, namely by using hybrid polymer solar cells structure with an inverted device architecture from the conventional, by reversing the nature of charge collection. In this paper we report the results of the fabrication of inverted bulk heterojunction polymer solar cells based on P3HT:PCBM as active layer, utilizing ZnO interlayer as buffer layer between the ITO and active layer with a stacked structure of ITO/ZnO/P3HT:PCBM/PEDOT:PSS/Ag. The ZnO interlayer is formed through short route, i.e. by dissolving ZnO nanoparticles powder in chloroform-methanol solvent blend rather than by sol-gel process. Based on the measurement results on electrical characteristics of inverted polymer solar cells under 500 W/m2 illumination and AM 1.5 direct filter at room temperature, cell with annealing process of active layer at 110 °C for 10 minutes results in higher cell performance than without annealing, with an open-circuit voltage of 0.21 volt, a short-circuit current density of 1.33 mA/cm2 , a fill factor of 43.1%, and a power conversion efficiency of 0.22%. The low cell’s performance is caused by very rough surface of ZnO interlayer.

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.
