Özet
We studied photocarrier dynamics in organic photovoltaics by terahertz time domain spectroscopy. Transient THz absorption decays in C60 and zinc phthalocyanine span a wide range of timescales and reveal how to optimize photocarrier yields. We find evidence for direct excitation of a charge transfer state of C60 and morphology dependent excitation of free carriers. © 2010 OSA/FiO/LS 2010.
