Theoretical study on the geometries,
electronic properties and absorption spectra of these five conjugated compounds
based on thiophene are studied by Density Functional Theory (DFT) method at
B3LYP level with 6-31G(d,p) basis set. 
The absorption properties were calculated starting at the optimized
structures are calculated using TD-B3LYP/6-31G(d,p) method. The HOMO, LUMO, Gap
energy, Voc , ionization potentials
(IP)/electron affinities (EA) and λmax   of these
compounds have been calculated and reported in this paper. The objective of
this study; is to evidence the relationship between chemical structure of these
organic materials and their properties optoelectronic and
photovoltaic of ways has conceive
thereafter the compounds with effective character for solar cells.
