Zusammenfassung:	A method is provided to adhere a lamina to a receiver element using a glass frit mixture. A donor body having a previously defined cleave plane and a receiver element are provided. The glass frit mixture is applied to either the donor body or the receiver element, or both, and is first dried to drive off solvents, then heated to burn out organics. If the glass frit mixture is applied to the receiver, the receiver element and glass frit mixture may be heated to the flow temperature of the frit. Following burn out of organics, the glass frit mixture will undergo no additional outgassing or densification. The receiver element and the donor body are then juxtaposed, the glass frit layer between them. The structure is heated further to permanently adhere the surfaces and to cleave a lamina from the donor body at the cleave plane. A device such as a photovoltaic cell is fabricated, the cell comprising the lamina.
