Available in PDF, EPUB and Kindle. Book excerpt: Silicon-Germanium Alloys for Photovoltaic Applications provides a comprehensive look at the use of Silicon-Germanium alloys Si1-xGex in photovoltaics. Different methods of Si1-xGex alloy deposition are reviewed, including their optical and material properties as function of Ge% are summarized, with SiGe use in photovoltaic applications analyzed. Fabrication and characterization of single junction Si1-xGex solar cells on Si using a-Si as emitter is discussed, with a focus on the effect of different Ge%. Further, the book highlights the use Si1-xGex as a template for lattice matched deposition of III-V layers on Si, along with its challenges and benefits, including financial aspects. Finally, fabrication and characterization of single junction GaAsxP1-x cells on Si via Si1-xGex is discussed, along with the simulation and modeling of graded SiGe layers and experimental model verification. - Includes a summary of SiGe alloys material properties relevant for solar research, all compiled at one place - Presents various simulation models and analysis of SiGe material properties on solar cell performance - Includes a cost-analysis for III-V/Si solar cells via SiGe alloys
