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%.

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.

In this study, extracted plumeria and celosia cristata flowers have been used as the sensitizer for dye-sensitized solar cells (DSSC). The cells were fabricated using TiO2 as a semiconductor layer deposited on transparent Indium doped tin oxide (ITO) conductive glass using a spin coating technique. The films with dyes were characterized by UV-VIS absorption spectra. The photovoltaic properties of DSSC were studied under an incident irradiation of 100 mW/cm2. The I-V characteristic curves of all fabricated cells were measured and analysed. The energy conversion efficiency (η) of the cells consisting of plumeria extract and celosia cristata extract was 3.73 × 10-6 and 1.18 × 10-7, respectively.

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.

Energy Disperse Spectroscopy

Pt-counter electrodes were manufactured by dip coating, spin coating and sputtering methods for dye-sensitized solar cells (DSSCs). Their properties were analyzed with cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), energy disperse spectroscopy (EDS). We also fabricated the TiO2 nanotubes of 1.04 μm length as photoanode. The analytic results show that spin coating method has higher Pt content deposited on FTO glass, better performance of charge-transfer, more positive potential of tri-iodide reduction and higher efficiency of DSSCs.
