Recent development of highly efficient organic conjugated materials based photonic and electronic devices has opened 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 and inorganic hybrid 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 will discuss the development of solution processible conjugated polymers and perovskites that can be used to enhance power conversion efficiency of solar cells. Several innovative strategies were also applied to modify the interface of bulk-heterojunction and planar-junction devices to create new device architectures with improved performance for printable semitransparent solar cells for building integration.
