Characterization of Microcrystalline and Amorphous Thin Film Silicon Devices with Raman Spectroscopy

Hodkiewicz J., Wall M., Thermo Fisher Scientific, US

Raman spectroscopy is highly sensitive to even slight changes in morphology of highly symmetrical, covalently bonded materials making it an ideal technique to characterize Silicon films. Furthermore, Raman spectroscopy is relatively insensitive to glass making [...]

Semiconductor Oxide Nanoparticles

Sharma A., Sharma R., Sharma A., Sharma R., Sharma A., Sharma R., AKG College of Engineering, IN

The nanoparticle hybrid systems are improved semiconductors. They are compared with their isolated counterparts. We report the preparation of MO2 (M = Ti, Ce, and Sn) and their synthesis. We report the controlled-size semiconductor oxide [...]

Shape Effect on the Reflectance of Sub-Wavelength Structures on Silicon Nitride for Solar Cell Application

Sahoo K.C., Li Y., Chang E.Y., National Chiao Tung University, TW

Sub-wavelength structure (SWS) on anti-reflection coating instead of semiconductor surface can improve the efficiency of silicon solar cell has been studied both numerically and experimentally recently. The shape of the SWS may be somewhat variable [...]

Multi Solar Desalination Plant

Elazari A., Millennium Electric T.O.U. LTD., IL

Desalination technology, which makes it possible to exploit sea water as a water source, is playing an increasingly important role throughout the world. However, its high energy consumption is costly (4-5kWh/1 cubic meter of desalinated [...]
