In this direction, the solar cells with the anode electrode of TiO2 nanoparticles were prepared. Porous layers by natural dyes, Hibiscus sabdariffa and Pokeweeds were sensitized. Results show that sensitized cells with Pokeweeds strongly absorbs light in the visible region and this leads to more efficient solar cells sensitized with this dye. M3 ER -
