Energy, Lighting and Display Research

A number of projects investigate three timely fields at the NEC. Extensive research is carried out on photovoltaic energy conversion, using nanotechnology. Organic light emitting diodes are another significant area of research. Also, electron field emission and circuit design research for displays are studied under a number of projects.

Photovoltaic research is broadly categorised in to three areas; organic, inorganic & hybrid systems. On the organic front, improvements to bulk heterojunction systems are investigated. Amorphous silicon solar cells are investigated for crystallisation using lasers, in the inorganic front. Hybrid systems involve small molecule/quantum dot and silicon/polymer systems.

On the organic light emitting devices, studies are carried out on the utilisation of carbon nanotubes as hole injection material for enhanced emission.

The field emission work has concentrated on carbon nanotubes and composites, and extensive work on modelling is carried out. Further driver circuit design is also pursued at the centre.
