Our laboratory is engaged in understanding the electronic and optoelectronic
processes in extended macromolecular systems. This knowledge is applied to
the development of devices, specifically solar cells and field-effect
transistors. Additionally, we explore bioelectronics, where soft-electronic
polymers are investigated for biophysical applications such as tissue
engineering and vision prosthetic elements.
Materials
Designing and characterizing new organic electronic materials is a core part
of our research. We collaborate with leading chemists to develop
high-mobility polymers, small molecules, and acceptor materials for bulk
heterojunction-based solar cells. We also explore high and low-k
dielectrics. A significant effort goes into optimizing processing conditions
to achieve desired properties, using tools like spin-coating, printing
methods, annealing under electric fields, soft-lithography, and vapor
deposition.
Devices
Our lab has studied a wide range of photovoltaic structures and
architectures, with a focus on developing large-area devices that offer low
manufacturing complexity.
We have pioneered the development of polymer-based optical field-effect
transistors, interfacing organic/polymer semiconductors with biological
media at the molecular, cellular, and system levels. Additional innovations
include large-area position sensors, stretchable and flexible light-emitting
diodes, resonant cavity near-infrared (NIR) high-speed detectors, and large
organic solar cell designs.
