About Me

We are trying to employ the recent advances of nanoscience and nanotechnology in order to develop smarter optoelectronic devices with the aspiration of pushing the limits of existing technologies. Our main scope of work is to synthesize new functional materials with tailored optical and electronic properties for optoelectronics and renewable energy applications. We are focusing on the development of next generation solar cells employing quantum dots, nano structures and organic molecules as active material for solar energy harnessing.
