Diketopyrrolopyrrole derivatives for bulk heterojunction and dye sensitised solar cells

Abstract

This thesis describes the synthesis and characterisation of a series of molecules for use in bulk heterojunction and dye sensitised solar cells. The target molecules were based on a central diketopyrrolopyrrole subunit. Molecules based on diketopyrrolopyrrole have a conjugated structure, allowing for π-π interaction. Diketopyrrolopyrrole molecules also have relatively low lying HOMO and LUMO levels and high absorption coefficients and exhibit efficient charge transport properties. Furthermore, their electron withdrawing properties have warranted their use as promising organic photovoltaic materials. A number of molecules were successfully synthesised and sent to collaborators for testing in organic photovoltaic devices and development of this series of molecules continues to be of interest within the research group.
