Molecular Opto and Bio-Electronics Lab 

Molecular opto-electronics is a field of material science concerning the design, fabrication, characterization, and application of organic small molecule or polymer based devices such as electrical-to-optical or optical-to-electrical tranducers or instruments that use such devices in their operation. In this aspect, our group tries to understand the optical and electrical properties of this system along with the possibility of making solar cells, light emitting diodes, field effect transistor and photodetectors.
