Advances in controlled synthesis, processing, and tuning of the properties of organic conjugated polymers and peroskites have enabled significantly enhanced performance of organic and hybrid solar cells. The performance of polymer and hybrid solar cells is strongly dependent on their efficiency in harvesting light, exciton dissociation, charge transport, and charge collection at the metal/organic/metal oxide or the metal/perovskite/metal oxide interfaces. In this talk, an integrated approach of combining material design, interface, and device engineering to significantly improve the performance of polymer and hybrid perovskite photovoltaic cells (PCE of ~19%) will be discussed. At the end, several new device architectures and optical engineering strategies to make tandem cells and semitransparent solar cells will be discussed to explore the full promise of polymer and perovskite hybrid solar cells.
NEW FRONTIER OF ORGANIC FUNCTIONAL MATERIALS AND DEVICES: FROM MOLECULAR ENGINEERING TO TECHNOLOGY INNOVATIONS

Recent development of highly efficient organic conjugated materials based photonic and electronic devices has opened the way to promising opportunities to complement and improve current inorganic semiconductor-based technologies. In this talk, two examples will be given based on molecular engineering of the shape, size, interactive force, interface and energy levels of organic conjugated materials to significantly improve the performance of devices for efficient energy generation and low power ultrafast information processing.
The first example will be focused on organic electro-optic (EO) materials that can be used to provide a full array of optical functions and can be processed at temperatures that are compatible with CMOS integrated circuits. In response to exponentially increasing demands for operational bandwidth, nanostructured organic EO materials are expected to play critical role in organic silicon hybrid nanophotonics in the near future. Integrated optical circuits based on organic silicon hybrid EO materials will enable low cost, mass production of novel nanophotonic devices for broadband optical signal processing and communications.
The second example is on the development of processible and high-charge carrier mobility conjugated polymers to enhance power conversion efficiency of solar cells. Several innovative strategies were also applied to modify the interface of solar devices and to create new device architectures to improve their performance for printable semitransparent solar cells for potential applications in solar windows.
