Originální abstrakt

ITO|active material|Al structures with active diphenyl-diketopyrrolopyrroles (DPP) films of about 150 nm thicknesses were prepared by vacuum deposition and encapsulated in an inert atmosphere. The surface morphology of the fabricated thin films was studied by SEM imaging, which revealed formation of grains with size of about 200-500 nm. Photoelectric characterization was carried out. Dark current measurements follow non-linear characteristics, with contact barrier of about 0.2 Vwere found. Photocurrent of almost two orders of magnitude higher than the dark current was obtained under an illumination of monochromatic light. Further increase of the photocurrent could be achieved by optimization of the solar cell structure.
