Effects of film thickness and electrolyte concentration on the photovoltaic performance of TiO2-based dye-sensitized solar cell (DSSC) were studied. Nanocrystalline anatase TiO2 thin films with varying thicknesses (3.2–18.9[Formula: see text][Formula: see text]m) have been deposited on FTO/glass substrates by screen printing method as work electrodes for DSSC. The prepared samples were characterized by UV-Vis spectroscopy, Atomic Force Microscopy/Scanning Tunneling Microscopy (AFM/STM) and X-ray diffraction (XRD). The optimal thickness of the TiO2 photoanode is 13.5[Formula: see text][Formula: see text]m. Short-circuit photocurrent density ([Formula: see text]) increases with film thickness due to enlargement of surface area whereas open-circuit voltage decreases with increase in thickness due to increase in electron diffusion length to the electrode. However, the [Formula: see text] and [Formula: see text] of DSSC with a film thickness of 18.9[Formula: see text][Formula: see text]m (7.5[Formula: see text]mA/cm2 and 0.687[Formula: see text]V) are smaller than those of DSSC with a TiO2 film thickness of 13.5[Formula: see text][Formula: see text]m (9.9[Formula: see text]mA/cm2 and 0.734[Formula: see text]V). This is because the increased thickness of TiO2 thin film resulted in the decrease in the transmittance of TiO2 thin films hence reducing the incident light intensity on the N719 dye. Photovoltaic performance also depends greatly on the redox couple concentration in iodide[Formula: see text]triiodide. [Formula: see text] decreases as the redox concentration increases as a result of increased viscosity of the solution which lowers ion mobility. Similarly, [Formula: see text] decreases as the electrolyte concentration increases due to enhanced back electron transfer reaction. An optimum power conversion efficiency of 4.3% was obtained in a DSSC with the TiO2 film thickness of 13.5[Formula: see text][Formula: see text]m and redox concentration of 0.03[Formula: see text]mol dm[Formula: see text] under AM 1.5G illumination at 100[Formula: see text]mW/cm2.

Dye-sensitized solar cell (DSSC) has attracted immense interest over the past decade due to its low cost and simplicity as a renewable energy source. In DSSC, the photo-anode that governs the collection and transportation of photo-excited electrons plays a critical role in determining the cell performance. In particular, the thickness of the photo-anode is known to be one of the decisive factors in dictating cell efficiency. In this paper, the thickness effect of TiO2 film as photo-anode on the photovoltaic performance of DSSC is studied. The TiO2 films were characterized by UV-visible absorbance spectroscopy to correlate the film thickness with the light harvesting efficiency of DSSC. The effects of film thickness on the photocurrent density-voltage characteristics of DSSCs were also investigated. The optimized thickness (4m) of the TiO2 film was discovered to be the best compromise between the amount of dye loading and the electron transport resistance.

Well crystallized Aluminium (Al) doped Titanium dioxide (TiO2) nanoparticles with various doping concentration (0, 0.05[Formula: see text]M, 0.07[Formula: see text]M, 0.09[Formula: see text]M and 0.11[Formula: see text]M) were synthesized successfully by sol–gel route to develop the photo anode of Dye Sensitized Solar Cell (DSSC). Anatase crystalline nature of TiO2 nanoparticles was confirmed using X-ray diffraction (XRD) and Raman spectrophotometer. The Atomic Force Microscopy (AFM) was used to investigate the morphology of the photo anode (Al-doped TiO2 nanoparticles). The photovoltaic performance of the DSSC in terms of Current, Voltage and efficiency was investigated with a standard illumination of AM1.5G having an irradiance 100[Formula: see text]mW/cm2. Optimized values of Short Circuit Current density ([Formula: see text]), Open Circuit Voltage ([Formula: see text]) and efficiency ([Formula: see text]) obtained was 247.62[Formula: see text][Formula: see text]A/cm2, 359[Formula: see text]mV and 0.02456%, respectively for 0.07[Formula: see text]M Al doping concentration. Eco-friendly Eosin Y dye was used for sensitization of the photo anode. The optimized photovoltaic cell exhibits very good efficiency (80.05% more than the earlier reported work).
