In this research investigation, natural dyes have been prepared from salvia and spathodea flowers for dye-sensitized solar cells (DSSCs). TiO 2 nanosphere-based thin films were prepared using the doctor blade method and the natural dyes were loaded on TiO 2 nanospheres. The electrochemical and photo...
