Synthesis and characterization of self-assembled, high aspect ratio nm-scale columnar silicon structures
(Institute of Electrical and Electronics Engineers Inc., 2013-06)
The aim of this work is to synthesize nm-scale columnar structures in Si principally for solar cell applications. These structures are also desirable as templates for heteroepitaxial growth of SixGe1-x. A nanostructured ...
An investigation of crystalline thin-film Six/Ge 1-x/Si solar cells
(Institute of Electrical and Electronics Engineers Inc., 2013-06)
Thin film solar cells have attracted a lot of attention due to their potential for increased efficiency and reduction in cost of material. Thin-film crystalline silicon solar cells are fundamentally limited in efficiency ...
Optimization of silver-assisted nano-pillar etching process in silicon
(Elsevier, 2015-12-01)
In this study, a respond surface methodology (RSM) model is developed using three-level Box-Behnken experimental design (BBD) technique. This model is developed to investigate the influence of metal-assisted chemical etching ...
Role of micro and nanostructures in enhancing near IR optical absorption in Silicon
(Institute of Electrical and Electronics Engineers Inc., 2014-10-15)
Role of micro and nanostructures in enhancing IR transmission in Si wafers has been investigated. Based on feature dimensions, incident light interaction can be described in terms of: (a) geometrical optics for wavelengths ...
Heteroepitaxial growth of vacuum-evaporated Si-Ge films on nanostructured silicon substrates
(Faculty of Science and Technology, Universiti Kebangsaan Malaysia, 2015)
In this study, a low-cost vacuum-evaporated technique is used in the heteroepitaxial growth of Si-Ge films. Three different surface variations are employed: i.e. polished Si, Si micropyramids and Si nanopillars profiles. ...
Investigation of XeF2 dry etching for contact isolation of screen printed IBC solar cell
(Institute of Electrical and Electronics Engineers Inc., 2013-06)
We demonstrated the use of Xenon Difluoride (XeF2) plasma less vapor etching for isolation of n and p regions in screen-printed interdigitated back contact (IBC) solar cell. The fabrication process is free from lithography ...
Optical characterization of SixGe1-x films grown on nanostructured Si substrates
(Institute of Electrical and Electronics Engineers Inc., 2014-10-15)
High quality Ge and SixGe1-x films grown on Si substrates are attractive for a wide range of applications in optics, optoelectronics, and high efficiency solar cells. In this study, heteroepitaxial growth of Ge on ...
Numerical analysis of bifacial solar cell using PC1D software
(Institute of Electrical and Electronics Engineers Inc., 2013-06)
Computer-based simulations play a critical role in the design, development, and functionality of solar cells. Device modeling techniques substantially reduce the time and costs through optimization of process steps, choice ...
PC1D analysis of thin-film crystalline SixGe1-x/Si solar cells
(Institute of Electrical and Electronics Engineers Inc., 2014-10-15)
Inability to achieve complete optical absorption in thin-film crystalline Si (TF c-Si) solar cells fundamentally limits efficiency. Therefore, materials with high absorption across the entire solar spectrum are highly ...
