摘要

A promising low-cost reflector material for solar concentrating power generation is a silvered substrate protected by an alumina coating several microns thick. The alumina coating is transparent and serves to protect the silver film from tarnishing. The coating is deposited under high vacuum by electron beam evaporation with an ion beam assist. Samples were first produced on polyester film several years ago in a box coater. Accelerated testing at the National Renewable Energy Laboratory (NREL) showed excellent optical durability. Recently samples have been produced by roll-coating onto a web of chrome-plated carbon steel 30.5-cm wide. The technical thrust of the work has been to increase the alumina deposition rate above 20 nm/s while maintaining high optical durability. In this paper we discuss the technical challenges encountered in depositing alumina onto a steel foil with a nominal deposition rate 20 nm/s.
