Dye-sensitized solar cells (DSSCs) have attracted the attention of scientists all over the world because of their relatively high efficiency and low-cost production. But in order to increase the ionic conductivity and reduce the fragility of electrodes, there is a tendency to substitute some of these materials by polymers. With the aim of understanding the electrical and physico-mechanical properties of polymer solar cell, we have fabricated and characterized an electro active nanocomposite using Na-alginate, Titanium dioxide (TiO2) and natural dye. The conductivities of nanocomposites with different wt,%TiO2 were studied with temperature. The highest conductivity (0.0472 S/m) was found for 8%TiO2 at room temperature which increased by 38.34% with rise in temperature. The mechanical properties of nanocomposites were also observed by means of Tensile Strength (TS) and Elongation at break (Eb). The alginate based nanocomposite with 8 wt% TiO2 showed highest TS of 16.31 MPa which was 454% greater than that of pure alginate. The UV-analysis of different compositions also justified the conductivity result.
