Photoinduced electron transfer in thin films of porphyrinfullerene dyad and perylenetetracarboxidiimide

Author affiliations

Abstract

Photoinduced intra- and intermolecular electron transfer (ET) in thin films of porphyrinfullerene dyad (P–F) and perylenetetracarboxidiimide (PTCDI) was studied by means of photoelectrical and spectroscopic methods. Films consisting of smooth 100 mol% layers of P–F and PTCDI were prepared by the Langmuir–Schäfer (LS) technique and thermal evaporation, respectively. The time-resolved Maxwell displacement charge (TRMDC) and laser flash-photolysis methods were utilized to demonstrate photoinduced ET from P–F to PTCDI regardless of which chromophore is photoexcited. Finally, the information about the electron movement in the respective thin films was used to build a layered organic solar cell, whose internal quantum yield (ΦI) of collected charges was 13%.
