| الوصف: | We studied photovoltaic effect in poly-dioctyl-phenylene-ethynylene (PPE)-C60 cells using photovoltage and photocurrent spectroscopy. We observe two-step photoexcitation dependence of open circuit voltage Voc. Two values of Voc are due to different Coulomb binding energies for carriers originated from excitons in PPE and C60. Due to built-in potential between PPE and C60 layers, carriers overcome this exciton binding energy and separate at the heterojunction. We describe our results by energy diagram, comparing exciton binding energies in donor and acceptor moieties. |
