In this work the energy levels and energy gaps of polymer solar cells values were found when there are doped with Coumarin, Lawsonia, Rohdamin B, Blue 8GX, Roselle, DDTTC and Ero-Chrom black, by means of the values of absorption and transmission spectra, beside values of absorption coefficient- intensity relations of them. The results obtained for shows that the absorption spectra which relates intensity and emitted wave lengths for them gives the values of donor and acceptor levels which are 5.07 , 4.41 , 5.08 5.12 4.57 4.88 5.54 respectively 2.43 2.25 2.45 2.84 2.32 , 2.41 2.33 respectively. The transmission spectra for Coumarin, Lawsonia, Rohdamin B, Blue 8GX, Roselle, DDTTC and Ero-Chrom black is closely related to their energy gaps which were found to be these values are in conformity with the results obtained by the absorption coefficient – intensity relations which predicts the energy gaps , and which are in agreement with the standard values.

Keywords: Polymer, Absorption, Transmitting spectra, Energy levels and Energy gaps.
