*Infrared Absorption and Heat-Resistant Materials

†††††† Infrared absorption and heat-resistant materials could greatly improve solar cell efficiency.† Heat energy from sun light is usually at infrared spectrum that is less than the energy band gap of light harvesting semiconductor in a typical solar cell. Infrared light and some visible light may waste as heat or just simply pass through the solar panel. Using a designed surface coater to absorb or reflect infrared light will enhance solar cell quality and efficiency.

 

 

 

 

 

 

 

 

*Microwave Absorbing Materials

†††††† The electromagnetic spectrum for detection purposes has been investigated intensively from ultra violet through visible, infrared, microwave and radio frequencies. Based on the same theory, conversely detection avoidance through absorbing materials also interests military applications.† The exploitation of microwave (radar) absorbing materials has a long history since the advent of radar in the 1930ís. Absorber design has incorporated materials with different loss mechanisms and has make use of physical optics to optimize absorption over wide bandwidths. Absorbers therefor come with many different materials, shapes and structures.†

 

*Thermoelectric Materials: Energy Conversion from Heat to Electricity

†††††† Thermoelectric effects enable direct conversion between thermal and electrical energy. Such devices provide an alternative for power generation and refrigeration. Promising thermoelectric materials show simultaneously high electrical conductivity, high thermoelectric power, and low thermal conductivity. These properties define thermoelectric materials with large molecular weights, complex crystal structure, and liquid-like transports. Thermoelectric system is an environment-friendly energy conversion technology with the advantages of small size, high reliability, no pollutants and feasibility in a wide temperature range.

 Dr. Fanís research currently focuses on design, growth, and characterization of novel materials with emphasis on nanoscale thin films. The project is to develop a fast, easy and low cost process to fabricate nanoporous metal oxide thin films and membranes for solar energy conversion, photocatalysis, and biomaterials detections. Dr. Fan is also interested in the optical, electronic and magnetic properties of organic/inorganic hybrid systems and bulk materials for the applications of molecular memory and spintronic devices. Now exploring 3 new research fields: Infrared Absorption and Heat-Resistant Materials; Microwave Absorbing Materials; Thermoelectric Materials: Energy Conversion from Heat to Electricity.
