TiO2 Nanotube-Based Dye-Sensitized Solar Cell Using New Photosensitizer with Enhanced Open-Circuit Voltage and Fill Factor

A series of copolymers P(VP-HEMA) composed of hydroxyl ethyl methacrylate (HEMA) and 4-vinyl pyridine (VP) were prepared by a solution copolymerization technique. Based on the copolymer P(VP-HEMA) prepared by the content of VP 50%, the amount of AIBN 3% and the optimized liquid electrolyte, a polymer solution electrolyte with concentration of 9.0% was formed. By addition of 1,4-dibromobutane into the solution, the copolymer gel electrolyte with higher conductivity 6.14mS/cm was prepared. Gelation is caused by the quaterisation between the group of pyridine in P(HEMA-VP) and 1,4-dibromobutane. Based on the copolymer gel electrolyte, a dye-sensitized solar cell was fabricated with short-circuit current of 13.62mA/cm2,open circuit voltage of 0.72V, fill factor of 0.5465 and an overall conversion efficiency of 5.24% under irradiation 100mW/cm2(AM1.5).

Dye Sensitized

The dye-sensitized solar cell performances influenced by radiant intensity and illuminated area in concentrating photovoltaic system are investigated experimentally and discussed theoretically. The results show that, under the same irradiated cells area, the short-circuit current is linearly increasing with the radiant intensity and the open-circuit voltage follows a logarithmic function of the radiant intensity. And, it is turned out that the short-circuit current and open-circuit voltage are obviously enhanced by increasing the illuminated cells surface area at the same radiant intensity. However, that growth trends will decline with an increase of the illuminated area. The reason is more defects involved in the process of increasing illumination area. All results can be interpreted using an equivalent circuit of a single diode model. A good agreement can be observed from the fitting curves. It is of great significance for current photovoltaic research.

Dye Sensitized

In this analytical approach we fabricate and characterized a Titanium Dioxide Dye sensitized solar cell using Doctor-Blade Technique. The samples were given annealing treatment at various time of 20, 30 and 40 minutes respectivelyat constant annealing temperature of 450oC. The device under test (DUT) were tested using a Kiethley 2400, source meter under A.M 1.5 (1000W/m2) illumination from a Newport class A solar simulator.The results shows that at the miscellaneous annealing time, the open circuit voltagesVoc= 0.28V, 0.30V and 0.29V, the short circuit current density Jsc=95.5ÂµAcm-2 , 104.1ÂµAcm-2and 105ÂµAcm-2, the fill factor FF= 0.411, 0.448 and 0.525 and the energy conversion efficiency, Î· = 0.011, 0.014 and 0.016 respectively.With best results of open circuit voltage Voc=0.30, short circuit current density Jsc= 105mAcm-2, fill factor FF= 0.525 and energy conversion efficiency Î·= 0.016 was achieved.It was observed that the power density, Fill Factor and efficiency increases with increasewith increase in annealing time.

Recombination Reactions

Nb2O5 layer were deposited on ZnO by using doctor blade method. The preparation of a bilayered ZnO/Nb2O5 photoanode was introduce for dye-sensitized solar cell (DSSC) application. Deposition of Nb2O5 layer on ZnO film improves power conversion efficiency of DSSCs. The ZnO/Nb2O5photoanode-based DSSCs show increase in photocurrent, open circuit voltage and conversion efficiency. The ZnO/Nb2O5 solar cell provides 50 mV increase of open circuit voltage, [Formula: see text] increment in current density and [Formula: see text] increment in efficiency as compare to ZnO-based DSSCs. We further analyzed the electron recombination properties of ZnO and ZnO/Nb2O5 by utilizing electrochemical impedance spectroscopy (EIS). The EIS analysis (Bode Plot) for ZnO/Nb2O5 photoanode show shifting of the peak related to electron recombination towards low frequency as compared to ZnO photoanode. Thus, there is an increase in lifetime of electrons in the ZnO/Nb2O5 photoanode, confirming that the recombination reactions are reduced in ZnO/Nb2O5 photoanode as compared to the ZnO.
