Price allocation guidelines January 1980: Low-cost solar array project

Description: The price allocation guidelines (PAG) are an integrated set of specific cost targets for several task areas within the Low-cost Solar Array (LSA) Project. PAG is a working tool of LSA Project management designed to provide consistent and meaningful guidelines for costs of polycrystalline silicon material, sheet, cells, encapsulants, and module manufacturing. It is expected that advanced photovoltaic concepts derived from industry and the research community can be developed so that it will be po… more

Modeling of silicon particle growth. Progress report

Description: Efforts at the Jet Propulsion Laboratory toward the production of pure polycrystaline silicon are centered on the concept of silicon particle growth in a fluidized bed reactor (FBR) and a continuous flow pyrolyzer (CFP). The CFP possibly can provide the seed particles which will be grown to larger sizes in the FBR. In both the reactors polycrystalline silicon is obtaned from the pyrolysis of silane. A part of the JPL effort is to develop a model of silicon particle growth for the purpose of pre… more

Proposed method for determining the thickness of glass in solar collector panels

Description: An analytical method has been developed for determining the minimum thickness for simply supported, rectangular glass plates subjected to uniform normal pressure environmental loads such as wind, earthquake, snow, and deadweight. The method consists of comparing an analytical prediction of the stress in the glass panel to a glass breakage stress determined from fracture mechanics considerations. Based on extensive analysis using the nonlinear finite element structural analysis program ARGUS, de… more

Modeling of silane pyrolysis in a continuous flow reactor. Low-Cost Solar Array Project

Description: Silane pyrolysis in a continuous flow pyrolyzer is a simple process that is currently being developed for producing solar cell grade silicon. The process involves complex phenomena, however, including thermal decomposition of silane, nucleation and growth of silicon particles, and mass and heat transfer. Modeling the effects of transport phenomena on silane pyrolysis in a continuous flow pyrolyzer is discussed. One- and two-dimensional models are developed to predict velocity, temperature, and … more

Purification of silicon by the silicon fluoride transport process. Thermochemical study

Description: A computer-assisted thermochemical equilibrium analysis was conducted for the silicon transport reaction: Si(s) + SiF/sub 4/(g) = (intermediates) = Si(s) + SiF/sub 4/(g). The calculations indicated that a substantial transport rate should be possible at temperatures of 1700/sup 0/K and one atmosphere pressure. Computations were made to determine whether the elemental impurities present in metallurgical-grade silicon would transfer in this process. It was concluded that aluminum, chromium, coppe… more

Reactor for simulation and acceleration of solar ultraviolet damage

Description: An environmental test chamber providing acceleration of uv radiation and precise temperature control (+- 1/sup 0/C) has been designed, constructed and tested. This chamber allows acceleration of solar ultraviolet up to 30 suns while maintaining temperature of the absorbing surface at 30/sup 0/C to 60/sup 0/C). This test chamber utilizes a filtered medium pressure mercury arc as the source of radiation, and a combination of selenium radiometer and silicon radiometer to monitor solar ultraviolet … more

Normative price for a manufactured product: the SAMICS methodology. Volume II. Analysis. JPL publication 78-98. [Solar Array Manufacturing Industry Costing Standards]

Description: The Solar Array Manufacturing Industry Costing Standards (SAMICS) provide standard formats, data, assumptions, and procedures for determining the price a hypothetical solar array manufacturer would have to be able to obtain in the market to realize a specified after-tax rate of return on equity for a specified level of production. This document presents the methodology and its theoretical background. It is contended that the model is sufficiently general to be used in any production-line manufa… more
