Physics, Materials Science and Device Engineering of Solution Processed Semiconductors(Polymers, Hybrid perovskites)

Our laboratory is geared for studies which help us in understanding the electronic and optoelectronic processes in extended macromolecular systems. We then utilize this knowledge for device development; specifically solar cells and field effect transistors. Besides this, we dabble in bioelectronics where we explore these soft-electronic polymers for biophysical problems and utilize it in tissue engineering and for vision prosthetic elements.

Materials

Design and characterising new organic electronic materials forms a major part of our activity. We actively collaborate with leading chemists in this field and provide feedback in the quest for developing high mobility polymers and small molecules, acceptor molecules for bulk heterojunction based solar cells, high and low-k dielectrics. We spent considerable effort in optimizing processing conditions for a desired property. Processing tools include spin-coating and printing methods, annealing under electric field conditions, soft-lithography approaches, vapor deposition

Devices

Range of photovoltaics structures and architecture have been studied in our laboratory. We specifically are interested in developing large-area devices with low manufacturing complexity.

The laboratory has pioneered in developing polymer based optical-field effect transistors, Interfacing Organic/polymer Semiconductors with Biological Media at molecular-cellular-system level, large-area position sensors, stretchable-flexible light emitting diodes, resonant cavity NIR high speed detectors, large organic solar cell designs.
