摘要

This report identifies potential health and safety hazards posed by feedstock materials and residuals generated in the large-scale manufacture of gallium arsenide alloy based multi-junction photovoltaic cells. Hazards were identified by studying detailed process-level data for the metallorganic chemical vapor deposition technique used in depositing GaAsP/GaInAS and AlGaAs/GaInAs multiple junction cells. In accidental situations, the large quantities of arsine and phosphine required as feedstocks for production of these cells may present health hazards to workers and to the public. Although large quantities of metallorganic compounds are also required as input feedstocks, there is little toxicologic data available on these compounds. Health to workers may also be adversely affected by the inhalation, during routine clean-up, of GaAs alloy particulate depoited on reactor walls. A fraction of these particulates may also be vented to the outside environment with other atmospheric exhaust gases and present a potential threat to public health. (ERA citation 12:032621)
