My lab’s primary research interests lies within the nanometer level design, synthesis and engineering of new organic materials which can function in electronic devices such as organic solar cells, organic light emitting diodes and organic thin film transistors. We do not limit ourselves to concepts in either small molecules or macromolecules (polymers) but rather explore both. Underlying our research is the need to explore and understand the physical processes and properties of the novel materials we design. Our interests also span from fundamental chemistry to the applied chemistry and even into development and commercialization. For example were applicable, we are interested in the development of environmentally friendly and responsible chemical processes which yield our novel materials or their chemical precursors or intermediates.
In this seminar, I will discuss our specific interest in a new bulk heterojunction solar cell device structure. This structure has not been previously reported in the literature but is closely aligned with the more common ‘Heeger’ bulk heterojunction cell (P3HT-C60 based cell).
In the context of this new cell structure, I will discuss our recent activities concerning the crystal engineering of boron subphthalocyanine for light absorption, liquid/low Tg arylamines for hole-transport, dendritic arylamines for hole-transporting and time-permitting the engineering of phase separating polymers.
