Investigated optical and elastic properties of Porous silicon: Theoretical study
(Elsevier Ltd., 2011-08)
Compatibility between experimental and theoretical works is achieved. Empirical Pseudopotential Method (EPM) is used to calculate the energy gap of Si which is found to be indirect. Features such as refractive index, optical ...
New optical features to enhance solar cell performance based on porous silicon surfaces
(Elsevier B.V., 2011-05)
Electrochemical etching is used to fabricate porous silicon (PS) surfaces for both sides of the Si wafer. The effect of PS on performance of Si solar cells is investigated and the reflected mirrors are manipulated to enhance ...
