Abstract
Optical and photovoltaic properties of metalorganic compound – nickel(II)bis(dithiobenzil) (NBDB) in different states (solution, vacuum deposited film, polymer composite) have been studied. Observed absorption spectra are explained by the formation of sandwich-aggregates in deposited films, which are absent in the solution and polymer composites. The study of photovoltage spectra shown, that both deposited and composite films are photosensitive at 500-1000 nm range, and quantum efficiency of photogeneration for the direct excitation of aggregates is greater than for the excitation of monomer molecules.
