MANUFACTURE OF MULTIJUNCTION SOLAR CELL DEVICES

摘要

The present invention relates to a method for manufacturing a multijunction solar cell device comprising the steps of providing a final base substrate; providing a first engineered substrate comprising a first zipper layer and a first seed layer; providing a second substrate; transferring the first seed layer to the final base substrate; forming at least one first solar cell layer on the first seed layer after transferring the first seed layer to the final base substrate thereby obtaining a first wafer structure; forming at least one second solar cell layer on the second substrate thereby obtaining a second wafer structure; and bonding the first and the second wafer structure to each other.
