简介
Development of highly efficient dye-sensitized solar cells (DSSCs) with good photovoltaic parameters is an active research area of current global interest. In this article, we provide a simple recipe for the fabrication of electrospun TiO2 nanorod-based efficient dye-sensitized solar cell using a Pechini-type sol. The Pechini-type sol of TiO2 nanofibers produces a highly porous and compact layer of TiO2 upon doctor-blading and sintering without the need for an adhesion and scattering layers or TiCl4 treatment. The best nanofiber DSSCs with an area of ∼0.28cm2 shows an efficiency of ∼4.2% under standard test conditions (100mW/cm2, 25°C and AM1.5 G) and an incident photon-to-electron conversion efficiency (IPCE) of ∼50%. Impedance measurements show lower charge transfer resistance that improved the fill factor. We believe that simple approaches such as the present one to develop nanofiber DSSCs …
