Ribbon Growth of Single Crystal GaAs for Solar Cell Application.
Abstract
This report describes the first 12 months of a program to develop GaAs dendritic web. Liquid encapsulation with B203 is used to suppress As vaporization from the melt. Standard web growth system design and experimental techniques which have been developed at Westinghouse for Si web are also utilized for the GaAs program. Critical optimization of thermal geometry is achieved with computerized thermal modeling. Dendritic growth and web buttoning of GaAs have been observed in the current program. Web crystals have not yet been produced, however, a piece of primitive web material has been recovered from the system. The growth behavior and the morphology of GaAs dendrites, buttons, and web material are analogous to the results obtained from successful Si and Ge web growth systems. The thermal modeling results also indicate that the liquid encapsulated GaAs system is suitable for web growth. (Author)
