Polycrystalline silicon (commonly known as "polysilicon") is the cloth of selection for photovoltaic (PV) purposes. Polysilicon is the purest man made fabric out there, although its processing via fuel purification and decomposition (commonly known as "Siemens" method) contains excessive environmental hazard. whereas many present optoelectronic functions require excessive purity, PV purposes don't and consequently trade techniques and fabrics are being explored for PV grade silicon. Solar Silicon strategies: applied sciences, demanding situations, and possibilities reviews present and strength destiny processing applied sciences for PV purposes of sunlight silicon. It describes substitute methods and problems with fabric purity, expense, and environmental effect. It covers limits of silicon use with appreciate to high-efficiency sun cells and demanding situations coming up from R&D actions. The booklet additionally defines purity necessities and purification approaches of metallurgical grade silicon (MG-Si) and examines creation of sun grade silicon via novel tactics at once from MG-Si and/or via decomposition of silane gasoline in a fluidized mattress reactor (FBR). in addition, the book:

• Analyzes earlier learn and commercial improvement of reasonably cheap silicon techniques in view of figuring out destiny traits during this field.








• Discusses demanding situations and chance of luck of varied sunlight silicon processes.








• Covers strategies which are extra environmentally sensitive.








• Describes limits of silicon use with appreciate to high-efficiency sunlight cells and demanding situations bobbing up from R&D actions.








• Defines purity specifications and purification tactics of MG-Si.








• Examines creation of sunlight grade silicon at once from MG-Si.
