ABSTRACT
The efforts to increase the efficiency of perovskite solar cells (PSC) as fourth
generation solar cells has been carried out, one of which to repair electron transport
layers made of titanium dioxide (TiO2) semiconductors. The TiO2 layer was
successfully grown on Fluorine Tin Oxide (FTO) substrate using the liquid phase
deposition method. The TiO2 layers were grown twice at 50oC. The first layer was
grown for 2 hours and the second layer was grown at different duration i.e 1 hr, 2 hr,
3 hr and 4 hr. The optical, structural, morphological, and elemental properties of the
samples were characterized using UV-Vis spectroscopy, X-Ray Diffraction (XRD),
Field Emission Scanning Electron Microscope (FESEM) and Energy Dispersive Xray
(EDX), respectively. TiO2 thin layer was then applied as an Electron Transport
Material (ETM) of the PSC with n-i-p configuration. The UV-Vis characterization
results showed that the peak absorption spectrum of TiO2 thin films occurred in the
wavelength range of 300-450 nm for all samples. Based on the UV-Vis absorption
spectrum, it was found that the TiO2 layer band gap energies value were 3.10 - 3.30
eV. The XRD pattern indicates the presence of anatase TiO2 with crystal orientation
(101), (004), (200), and (105) at the diffraction peak angle 2θ: 25.50o, 37.92o, 48.04o,
54.84o. FESEM characterization showed that the longer growing time, causes more
TiO2 particles covering the FTO layer. The EDX data for sample T2-0 showed that
there are still Sn elements because of uneven FTO surface covered by TiO2. The
results of cell performance measured under halogen light with the power of 100
mWcm-2 give the best efficiency value which is 0.23% for cells using two-layer TiO2
with a growing time of 2 hours for the first layer (T2-0) and 2 hours for the second
layer at a temperature of 50ºC.
