Optical characterization of P3HT: PCBM (poly (3-hexylthiophene-2,5-diyl)): ([6,6] -phenyl C61 methyl ester of butyric acid) and PEDOT: PSS (layers of poly (3,4-ethylenedioxythiophene) ))) thin films deposited using the Spin Coating technique were studied using an effective medium approximation method (EMA). This method involves transmittance, reflectance and absorbance measurements, which describe the changes in their optical properties depending on the compositional balance of the materials involved.
The optical results were compared with the electrical characterization of each of by separated, and also has been performed for the Organic solar cells based on P3HT:PCBM deposited on ITO substrate by means the I-V characterization.
The results obtained on the organic solar cells shows a dark current density of 1.28 mA/cm2, a fill factor FF of 0.65 and a conversion efficiency of 1.01% for P3HT:PCBM solar cell.The perspective is improve the efficiency of organic solar cells by texturing techniques and nano-particles (colloidal crystal inside the active layer).
