High Infrared Reflectivity ITO Nano Powder Used in Flat Panel Display
ITO film because of its transparent,
conductive excellent performance and widely used. The main application areas
with flat-panel liquid crystal display (LCD), electroluminescence (ELD), a
solar cell transparent electrode; selectivity due to its light waves (high
transmittance of visible light, infrared light on the far higher reflectivity)
can be used as low-E glass, architectural glass windows for the cold region
acts as a thermal barrier, using low-E glass heat transmission loss in high
latitudes can be reduced about 40%; the ITO conductive glass, can be used in
place need to shield electromagnetic waves The computer room, on the radar
shield protected area even stealth aircraft, anti-electromagnetic interference
can be a transparent screen window or shield; the refractive index of the ITO
film (in the range of 1.8 to 1.9) and electrical conductivity, it is suitable
for use in antireflection coatings and photocurrent collection silicon solar
cells, light-heat conversion and utilization, as the effective use of solar
heat selective permeable membrane, the heat energy effectively "trap"
to the solar collector.
Based DC magnetron sputtering, metal
organic chemical vapor deposition and newly developed sol - gel technology
development ripe, ITO film has gained practical applications in many fields,
industrialization continued development of increasingly mature. But because
indium is scattered elements in nature low stocks, the price is higher, the
researchers are also looking for more cost-effective transparent conductive
film, ZnO film doped with aluminum is recognized as one of the materials most
development potential.
Now, with large-screen, high-definition LCD
universal, deprivation and environmental protection of the world's energy
needs, but also reflects the good prospects for the development of solar cells
in the near future as the representative of the theoretical study ITO
transparent conductive film and the actual applications will move to a new
level.
