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).

Titanium dioxide (TiO[Formula: see text] nanoparticles have been synthesized by the cost effective Sol–Gel technique. Characteristics of TiO2 nanoparticles were investigated by X-ray diffraction and Fourier Transform Infrared spectroscopy. The Eosin Y dye and dye extracted from Hibiscus tea have been successfully used in fabrication of the dye sensitized solar cell. The photovoltaic performance of the dye sensitized solar cell indicates that the short circuit photo current, open circuit voltage and efficiency of the DSSC using Eosin Y dye is 10 times more compared to the DSSC using the Hibiscus dye.

AbstractThis study reports the performance analysis of an organic dye-sensitized solar cell (DSSC), introducing MnO2 as an electron transport layer in TiO2/MnO2 bilayer assembly. The DSSCs have been fabricated using TiO2 and TiO2/MnO2 layer-by-layer architecture films onto fluorine-doped tin oxide (FTO) glass and sensitized with natural dye extracted from Malvaviscus penduliflorus flower in ethanol medium. The counter electrode was prepared to layer copper powder containing paste onto FTO's conductive side by the doctor's blade method. The optical, morphological, and structural properties of photoanodes were explored via ultraviolet–visible, field emission scanning electron microscopy, and X-ray diffraction analyses. Moreover, dye complexity and thermostability of dyes were characterized via Fourier-transform infrared spectroscopy and thermogravimetric analyses. The iodide/triiodide (i.e., I−/I3−) redox couple of electrolyte solution was employed as a charge transport medium between the electrodes. Finally, photoanode and counter electrode sandwiches were assembled to envisage the photovoltaic performance potential under simulated AM 1.5G solar illumination using 100 mW cm–2 light intensity. The as-fabricated DSSC comprising TiO2/MnO2 bilayer assembly exhibited 6.02 mA cm–2 short circuit current density (Jsc), 0.38 V open-circuit voltage (Voc), 40.38% fill factor, and 0.92% conversion efficiency, which is about 200% higher compared to the assembly devoid of MnO2 layer.

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.

Morphological Studies

In this investigation, anatase nanocrystalline TiO2 (nc-TiO2) films are deposited by using sol-gel dip coating method on ITO substrates followed by annealing at 200, 300, 400 and 500 °C / 2 hr in air. To examine the structure and morphology of films, XRD, Raman spectroscopy, SEM and HRTEM techniques are used. The XRD studies showed the evolution of pure anatase TiO2 phase with average crystallite size = 12-15 nm in resultant films. The morphological studies using SEM and HRTEM indicated ~ uniform size distribution of spherical agglomerates in films and nanocrystalline state of films (average particle size ~ 20 nm) respectively. The optical properties calculated from UV-Visible transmission spectra are found to be indirect band gap energy = 3.20 eV, absorbance coefficient = 9.2 x 104 cm-1, transmittance = 88.5 %, refractive index = 2.12 and porosity ratio = 36.6 % for the 400 °C annealed film. The better photovoltaic performance: JSC = 2.34 mA/cm2, VOC = 0.562V, FF = 35.23 % & η = 0.46 % is obtained for eosin-Y dye sensitized solar cell made with 400 °C annealed film.

Dye Sensitized

In order to overwhelm the electrolyte leakage problem and improve the stability in extreme climate conditions, we have studied the fabrication and characteristics of dye sensitized solar cell (DSSC) using polymer gel electrolyte (PGE), which is developed from siloxane based polymer gel blended with imidazolium ionic liquid. In many cases, the use of PGE often reduces its photovoltaic performance due to the decrease in its ionic mobility. However, such influence was not observed in our present work. In this work, the fabricated DSSC do not exhibit significant degradation in its working performance. The best overall energy conversion efficiency is about 5.25%, as indicated by short circuit photocurrent (Jsc) larger than 12 mA/cm2, which is comparable to performance of reference cell made by using ionic liquid only. We found from the impedance spectroscopy measurements that the electrolyte diffusion coefficient in the DSSC using this PGE is comparable to that in DSSC using ionic liquid electrolyte.
