Progress toward goals in silicon sheet developmentOne of the goals of the national photovoltaic program in the U.S. is the establishment of an industry producing photovoltaic material which can be sold at a price not exceeding $0.70/W by 1986. A key element concerning the achievement of this goal is the development and utilization of improved methods for producing silicon sheet. Specific technologies being investigated in this connection can be divided into two categories. Methods of one category are based on a utilization of sheet growth techniques including film-fed growth, dendritic web, and silicon-on-ceramic processes. The approaches used by methods of the second category involve ingot and wafering processes, including Czochralski growth, the heat exchanger method, multiblade procedures, and the use of a fixed abrasive multiwire. It is found that using $84/kg silicon, most sheet technologies would yield module prices in the $2.00/Wp to $3.00/Wp range.
