In this paper we report photovoltaic devices fabricated from PbS nanocrystals and the conducting polymer poly MEH-PPV. This composite material was produced via a new single-pot synthesis which solves many of the issues associated with existing methods. Our devices have white light power conversion efficiencies under AM1.5 illumination of 0.7% and single wavelength conversion efficiencies of 1.1%. Additionally, they exhibit remarkably good ideality factors (n=1.15). Our measurements show that these composites have significant potential as soft optoelectronic materials.
