Dye Sensitized Solar Cells (DSSCs) represent an attractive photovoltaic technology, and initially developed on glass substrates. The low-cost, lightweight, and flexible plastic substrates have been investigated for the fabrication of DSSC electrodes. A major challenge for making DSSCs on flexible plastic substrates is the temperature limitation in producing working electrode, since the electrode consists of TiO₂ based materials, which need high temperature calcination at around 450 C. In the present work, self-standing, mechanically flexible nanofiber mat of silica suitable for application in DSSC as thermally stable lightweight substrate has been prepared by the electrospinning method, and covered by a conductive layer of ITO.
