SOLAR BREEDER:ENERGY PAYBACK TIME FOR SILICON PHOTOVOLTAIC SYSTEMS First Quarterly Report, December 20, 1976-Mardh 20, 1977

摘要

The primary objective of this program of research is the characterization of the energy requirements and energy pro¬duction potentials of the "Solar Breeder" concept. This quarterly report documents the results of a careful and exten¬sive study undertaken at the SOLAREX CORPORATION to assess the energy expenditures of the prevailing manufacturing technology of terrestrial photovoltaic cells and panels. The five major production processes in the current technology are:silicon reduction, silicon refinement, crystal growth, cell processing and panel building.
