| dc.description.abstract | The low material costs and the ease fabrication procedures of organic solar cells has earned them too much interest from scientists all over the world. Much of the e orts were given to the improvement of the power conversion e ciency ( ) and the durability of the organic solar cells. Organic solar cells with the structure ITO/PEDOT:PSS/P3HT:PCBM/LiF/Al were fabricated under ambient laboratory conditions and J-V characteristics were studied. The active layers were composed of P3HT:PCBM blend. Power conversion e ciencies close to 2% and ll-factor as high as 60% were obtained. Stoichiometric ratio of the polymers P3HT:PCBM at 1:0.8 was observed to give the best performing samples. The samples were thermally annealed to enhance the optical properties of the devices by recovering the ordering or crystallization in P3HT and PCBM. | en |
