Organic Electronics & Nanomaterials

1. Organic Solar Cells : Polymer solar cells produces electricity from sunlight using polymers. It is a relatively novel technology. Many solar cells in the world are made from a refined, highly purified silicon crystal, similar to those used in the manufacture of integrated circuits and computer chips.

2. Light Emitting Diode : Polymer Electroluminescence Displays

Electroluminescence (EL) is the conversion of electrical energy into light. Light-emitting diodes (LED), based on conjugated polymers are intensively studied for potential application in large flat panel displays with low driving voltages. Electroluminescence in conjugated polymers occurs via the recombination of electrons injected into the conduction band and holes injected into the valence band.

3. Nanopatterning : Using by silicon master mold and colloidal crystal, A colloidal crystal is a highly ordered array of monodispere colloidal particles which can be formed over a long range. Colloidal crystals have been extensively studied over the past decade because of their potential applications in optoelectronic devices, photonic band gap materials, biological and chemical sensors, or catalysis. Especially, because of its nano scale regular structure colloidal crystals are promising materials for producing nanopatterns.

4. Metal Nanocrystals and their applications in Organic Electronics

Au and Ag nanoparticles plays an important role of enhancing light absorption at the active layer due to scattering and plasmonic effect. We are working on several different shape and sizes of metal nanocrystals related to the device performances, especially organic solar cells and LED.
