In this work dye polymer thin films solar cells were used in order to find both the value of energy gap and efficiency of solar cells. Samples of polymers were dye with chemical dyes such as Chrome, DDTTC, Blue 8GX, Rohdamin and Coumarin also natural dyes such as Hibscus and Lawsonia. Then values of gap energy and efficiency under effect of these dyes were tabulated.

Keywords: polymer, efficiency, energy gap, natural dyes, chemical dyes
