Abstract: The present disclosure provides a process for manufacturing a solar cell by selectively freeing an epitaxial layer from a single crystal substrate upon which it was grown. In some embodiments the process includes, among other things, providing a first substrate; depositing a separation layer on said first substrate; depositing on said separation layer a sequence of layers of semiconductor material forming a solar cell; mounting and bonding a flexible support on top of the sequence of layers; etching said separation layer while applying an agitating action to the etchant solution so as to remove said flexible support with said epitaxial layer from said first substrate.
