Abstract
A method of manufacturing a solar cell by providing a gallium arsenide carrier with a prepared bonding surface; providing a sapphire substrate; bonding the gallium arsenide carrier and the sapphire substrate to produce a composite structure; detaching the bulk of the gallium arsenide carrier from the composite structure, leaving a gallium arsenide growth substrate on the sapphire substrate; and depositing a sequence of layers of semiconductor material forming a solar cell on the growth substrate. For some solar cells, the method further includes mounting a surrogate second substrate on top of the sequence of layers of semiconductor material forming a solar cell; and removing the growth substrate.
