Modelling and Validation of Transmittance from Nanocrystalline Titania film for Photoanodic Action in Dye-Sensitized Solar Cells

AbstractA four phase model air/glass/indium doped tin oxide/TiO2 has been studied by modifying Rouard’s model to calculate the final transmittance from TiO2 layer to be used as photoanode in dye-sensitized solar cells. An optical simulation for the reflectance and transmittance has been executed for the constructed nanocrystalline TiO2 films. To validate the theoretical results TiO2 film has been deposited onto indium doped tin oxide (ITO) layer by sol-gel dip coating technique. It has been found that the incident light suffers losses by 5-15% on passage through TiO2 coated ITO layer. Experimentally it has been observed on the basis of efficiency value that meso-nano combination is the best candidate to be used as photoanode in a dye-sensitize solar cell.

A theoretical explanation of optics behind TiO2has been presented with the help of a four phase model air/glass/ indium doped tin oxide/TiO2designed by modifying Rouard’s model to calculate the final transmittance in to TiO2layer. An optical simulation for the reflectance and transmittance has been executed for the synthesized nanocrystalline TiO2films. To validate the theoretical results TiO2film has been deposited onto indium doped tin oxide (ITO) layer by sol-gel dip coating technique. The novelty of the task lies behind the fact that transmittance helps to calculate the light harvesting efficiency of the Dye-Sensitized solar cells which is the ratio of light actually harvested to the light actually reached to TiO2layer, and that can be done only if one knows transmittance.

In this work, the transparent TiO2 photoelectrodes have been synthesized by the sol?gel method and the dip-coating technique, incorporating three rheological agents as porous template ? Triton X-100, polivinilpirrolidone (M.W. 10000) and Pluronic F-127 into the TiO2 sol for the application in dye- -sensitized solar cells. Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, m-lines and UV?Vis spectroscopy analyses were carried out to examine the chemical composition, structure, morphology, thickness and optical transmittance of the TiO2 photoelectrodes. Impedance spectroscopy was carried out to analyze the cells? behaviour. An average energy conversion efficiency of 1.04 % was achieved using triton as a modifier of the transparent TiO2 film, obtaining a thickness about 1.21 ?m, a crystallite size of about 7 nm in the anatase phase and the porosity of about 53.4 %. Triton proved to be efficient for obtaining transparent and porous semiconductor films, while increasing the photoelectrochemical device?s performance.

Telah dilakukan pembuatan Dye Sensitized Solar Cells (DSSC) dengan elektroda kerja yang terbuat dari campuran TiO2 dan 14% grafit yang selanjutnya ditulis sebagai TiO2:C14%.Koloid TiO2:C14% dideposisikan pada substrat kaca konduktif Fluorine Doped Tin Oxide(FTO) dengan metode sol-gel-spin coating pada kecepatan 500, 1000 dan 1500 rpm selama 50 detik. Kemudian lapisan ini direndam selama 24 jam dalam pewarna (dye) yang diambil dari ekstrak kelopak bunga rosella (hibiscus sabdariffa). Untuk mengkarakterisasi bahan pembentuk sel surya dilakukan uji XRD dan SEM. Uji efisiensi sel surya tersensitasi zat warna dihitung dengan menggunakan rangkaian karakteristik kurva IV. Dari hasil yang diperoleh ketebalan tertinggi diperoleh pada kecepatan putar 500 rpm dengan ketebalan lapisan 0,9 mm dan efisiensi yang dihasilkan adalah 0,014%. The production of Dye Sensitized Solar Cells (DSSC) has been done. The transparent electrode is made by mixing of TiO2 and graphite 14% (TiO2:C14%). TiO2:C14% colloid is deposited on a conductive glass substrate Fluorine Doped Tin Oxide (FTO) by spin coating method at 500, 1000 and 1500 rpm during 50 second. Then, the layer is soaked of 24 hours in dye taken from the extract of rosella. SEM and XRD characterization are performed for looking properties of DSSC materials.

Sensitized Solar Cells

Photo-voltaic (PV) devices such as a Dye-Sensitized Solar Cell (DSSC) is a source of energy that converts incident photon or solar radiation to usable electricity. DSSCs are fast becoming a viable and interesting alternative to the traditional inorganic photo-voltaic devices to address the demerits of the inorganic PV devices like the use of expensive noble metals and high-cost chemical synthesis processes. A DSSC functions with two main components, i.e., a photo-sensitizer that absorbs incident light and a semiconductor onto which it is adhered to and a conductive glass housing such as Florine-doped Tin Oxide (FTO) or Indium-doped Tin Oxide (ITO), between which the sensitizer, semiconductor and an electrolyte are sandwiched. The semiconductor is preferably a wide-band semiconductor, of which the commonly used semiconductors in a DSSC are made of a nanoparticle layer of Titanium dioxide (TiO2), Zinc oxide (ZnO) and Tin oxide (SnO2). The utility of these solar cells with a diverse number of natural photo-sensitizers for use as an alternative PV device is described. Currently, there are an abundance of natural sources that could be used to obtain photo-sensitizers from, such as, micro and macro algae, plants, bacteria, etc. leading to increased importance in renewable energy sector and has gained traction to be a viable renewable energy resource. In addition to the functioning of an organic DSSC, various characteristics of the pigments used as photo-sensitizers are described here. Patents filed regarding eco-friendly and natural Dye-Sensitized Solar Cells have been increasing as of late and holds substantial promise.
