APPARATUS AND METHOD FOR PRODUCING SOLAR CELLS

摘要

A method and apparatus for forming a solar cell. The apparatus includes a housing defining a vacuum chamber and a rotatable substrate apparatus configured to hold a plurality of substrates on a plurality of surfaces wherein each of the plurality of surfaces are disposed facing an interior surface of the vacuum chamber. A first sputtering source is configured to deposit a plurality of absorber layer atoms of a first type over at least a portion of a surface of each one of the plurality of substrates. An evaporation source is disposed in a first subchamber of the vacuum chamber and configured to deposit a plurality of absorber layer atoms of a second type over at least a portion of the surface of each one of the plurality of substrates. A first isolation source is configured to isolate the evaporation source from the first sputtering source.
