Hybrid solar cells based on CuInS2 and MEH-PPV

Nanocomposite solar cells[1] will play a key role in the rapidly developing area of organic solar cells due to the possibility of low cost technology. Now there is much emphasis placed on the development of suitable materials for these applications which is the subject of our scientific effort. For realizing hybrid solar cells we used a mixture of CuInS2 nanoparticles (produced in a colloidal synthesis and stabilized with triphenyl phosphite (TPP)) and MEH-PPV (2-methoxy-5-(2?-ethyl-hexyloxy)-1,4- phenylene-vinylene).[2] Thin layers of ITO (indium tin oxide) and calcium aluminium were used as electrodes. Because of the strong influence of the morphology of the active layer they were investigated with atomic force microscopy (AFM). The electric properties of these devices were investigated by current/voltage - characterization under dark conditions and illumination.
