dc.description.abstract | The time-dependent photoconductivity of MDMO-PPV:PCBM blend films was studied using a microwave conductivity technique. The dependence of the photoconductivity on the weight fraction PCBM (W-PCBM) differs for the spin-coating solvents used, i.e. chlorobenzene (CB) or toluene. In the presence of PCBM-rich aggregates due to phase separation, the microwave conductivity is dominated by the electrons in the aggregates, resulting in a much slower decay. Despite large differences in morphology, the photoconductivity in films with W-PCBM = 0.75 spin-coated from CB is only three times higher than for the corresponding film from toluene. This is attributed to the large electron diffusion length within the MDMO-PPV:PCBM matrix (ca. 45 nm). Implications of the results for photovoltaic cells are discussed. (c) 2005 Elsevier B.V.
