Abstract:

Organic solar cells consisting of Phthalocyaninatocopper (PcCu) as donor and the Buckminsterfullerene C₆₀ as acceptor molecule were prepared by physical vapor deposition as planar or bulk heterojunctions. The devices were studied by IV-characterization as well as intensity-modulated photovoltage spectroscopy to determine the average lifetime of charge carriers formed subsequent to light absorption. An increasing charge carrier lifetime was determined for an increasing PcCu-content in the films. Back transfer of electrons at the undesired contact of C₆₀ with PEDOT:PSS as well as recombination following hole trapping in interface states in the contact of PcCu with C₆₀ or in isolated domains of PcCu are discussed as possible origins.
