Photocarrier generation quantum yield for ionically self-assembled monolayers

摘要

We have fabricated photovoltaic cells from organic donor/acceptor couples arranged as ionically self assembled monolayers. Making use of the morphological control on the nanometer level we were able to study the influence of the device structure and layer composition on the quantum yield of charge carrier photogeneration. The photoluminescence quenching and the photocurrent spectra reveal sample composition, charge carrier photogeneration and transport properties independently.
