| Abstract | Dye-sensitized solar cells are one of the most promising new generation of photovoltaic cells due to their low cost, easy fabrication and high energy conversion. One of the key components is photoanode that supports dye molecules and helps in the electron transfer. Titanium dioxide film used as a photoanode should have nanocrystalline structure, mesoporous nature and be semi-transparent. A thin semiconductor layer consist of nanocrystalline grains, therefore, DSSCs are also called nanocrystalline solar cells. Transparency is also an important issue of photovoltaic cells, especially when used in building integrated photovoltaics (BIPV) on glass and metal substrates. Moreover, the transparency allows their use in tandem cells. The paper presents the results of the structure investigation of a photoanode in dye-sensitized solar cells using the titanium dioxide. Solar cells were fabricated on the glass with TCO. The titanium dioxide films were deposited on TCO glass by screen printing method. Then the TiO2 electrode was immersed in N3 dye. Scanning Electron Microscopy images of titania films on substrates were observed. Light transmittance and absorbance of titania films with and without dye on TCO glass were measured by using a UV-Visible spectrophotometer. X-ray diffraction was employed to characterize the structures of photoelectrodes. |
