     In the present work, ZnSe nanocrystals doped (NCs) with selenium (ZnSe:Se) were synthesized and characterized. The impact of the concentration of ZnSe:Se NCs nanocrystals on the properties of the Poly(3-hexylthiophene-2,5-diyl) (P3HT) matrix was studied with a collection of experimental and theoretical investigations of this organic-inorganic hybrid structure. The optical absorption spectra were found to be strongly dependent on the level of ZnSe:Se NCs. Theoretical analysis provided insight into the experimental data for the explanation of energy and charge transfer. The Benesi-Hildebrand diagram was use to prove the complex formation in our layers.
