Originální abstrakt

The possibilities of improving the photovoltaic performance of solution processed BHJ solar cells by solvent vapor annealing of the active layers, based on a squaraine dye Sq1 as donor and fullerene derivative PCBM as acceptor, are studied. For the purpose, the optical properties of as-deposited and annealed with THF vapors for different duration Sq1/PCMB layers as well as the efficiency of constructed on their base cells are determined. A considerable change in the absorption spectra of treated for only a few seconds’ films and a twofold increase of power conversion efficiency for only 6 sec SVA have been established. The results obtained are explained in terms of solvent vapor induced phase separation and formation of squaraine dye small aggregates in the blend nanostructure.
