Organic Optoelectronics is an area of active research interests. Low weight, flexibility, large area scaling are some of the attributes which make its propositions attractive. 
My current interest is to investigate the different aspects of organic electronics. Potential applications include Organic light emitting diodes (OLEDs), Organic Non-volatile memories (OVMs), Organic Field Effect transistors (OFETs), Organic Photovoltaics (OPVs). Proper choice of materials, tuning the transport properties, proper balance of electron-hole pair gereneration and collection can make these devices viable.
Moreover, solution processed large scale integration can lead to printable electronics.
