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.

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. The efficiency of DSSC is calculated by using the characteristic circuit IV curve. The highest efficiency value is obtained when the thickest active layer (0,9 mm) at 500 rpm, the resulting efficiency is 0,014%.

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.

Dye-sensitized solar cells (DSSCs) have attracted many researchers because it has potential to supplement and compete with other solar cell technologies like Silicon (Si) and Cadmium Telluride (CdTe). The fabrication of DSSCs requires a photo electrode and a counter electrode of transparent and conducting nature. The commercial DSSCs uses electrodes of fluorine doped tin oxide (FTO) glass substrates. These electrodes are expensive and hence, possible alternative materials that are cheaper and that would provide better performance under similar environmental condition should be explored. In this paper, titanium (Ti)-coated glass substrates were prepared and then used to prepare electrodes for fabricating DSSCs. Similarly, DSSCs were fabricated using electrodes of conventional FTO-coated glass substrates. Performance characteristics like cell efficiency (η%), fill-factor (FF), short circuit current density (JSC) and open circuit voltage (VOC) of both fabricated DSSCs were obtained using their respective J-V characteristic curves under similar illumination of 100 mW/cm2 and with comparable transmittance under the visible transmission spectrum of 300-850 nm. The obtained results showed that DSSCs prepared using electrodes of FTO coated glass substrates have 1.557 times better cell efficiency and 2.172 times better fill factor than that of DSSCs fabricated using electrodes of Ti-coated glass substrates.
