Harnessing Solar Energy with Organic and Hybrid Photovoltaic Cells

Organic and hybrid solar cells are currently attracting significant interest due to a number of advantageous characteristics such as material diversity, mechanical flexibility, low-temperature processing, and large-area capability. To increase the photovoltaic response of organic solar cells, our efforts aim to address a number of fundamental issues, including: optical absorption and exciton formation; exciton dissociation and charge separation; charge carrier mobility; and charge collection at the electrodes.

We are also particularly interested in donor-acceptor (DA), i.e., low band gap, polymers that have recently garnered considerable use in bulk-heterojunction (BHJ) solar cells because of their wider photon absorption window. These polymers offer the promise of fabricating organic solar cells through solution-processing methods, which can further ease the processing demands and lower production costs. To design materials that improve overall device efficiency, we seek to understand the evolution of the structural, electronic, and optical properties of low band gap polymers that serve as the electron-donor and photon collector in bulk heterojunction solar cells. Recently, we have also become interested in evaluating the impact of coherence effects in the charge-separation process.

Charge and Spin Transport in π-Conjugated Materials

To develop molecular and polymer organic semiconductors with high charge-carrier mobilities in the semiconducting or metallic regime, a major challenge and opportunity lies in the understanding the inherent charge-transport mechanism.  In the absence of chemical and physical defects, the nature of charge transport depends on a subtle interplay between electronic and electron-vibration interactions.  A significant portion of our work centers on determining molecular and crystal electronic structures and evaluating electronic polarization effects in the solid state.  New developments include the evaluation of spin transport properties, as well as the characterization of the parameters describing the charge-voltage curves in organic field-effect transistors.

Organic Electroluminescence for Light-Emitting Diode Applications

Organic light-emitting diodes (OLEDs) offer tremendous potential for use in full-color displays and solid-state lighting. To gain a better understanding of the electronic and optical processes in OLEDs, we investigate numerous aspects, including: charge and energy transfer; aggregation effects on the electronic structure of the ground and excited states; electronic properties of host and guest materials; spin-orbit effects in organic and organo-metallic emitting complexes; and thermally assisted delayed fluorescence.

Two-Dimensional 2D Conjugated Polymers

Novel organic materials based on monolayers of two-dimensional conjugated polymers could provide unusual electronic, optical, electrical, and magnetic properties.  Together with our experimental partners, we are evaluating the impact of the two-dimensional characteristics and the interaction of these 2D polymers with other layered materials.
