Patent ID: 7964431

Claim:
A method for forming a photovoltaic assembly, the method comprising: bonding a first surface of a semiconductor donor body to a receiver element, with zero, one, or more layers intervening; cleaving a semiconductor lamina from the donor body at a cleave plane, wherein the first surface of the donor body is the first surface of the lamina and remains bonded to the receiver element, and wherein a second surface is created by cleaving, the second surface opposite the first; after the cleaving step, forming first conductive fingers and second conductive fingers, wherein the lamina is between the first fingers and the receiver element, and between the second fingers and the receiver element; and forming a photovoltaic cell, wherein the photovoltaic assembly comprises the lamina, the receiver element, and the photovoltaic cell, wherein, during normal operation of the cell, photocurrent flows from the first fingers to the second fingers or from the second fingers to the first fingers, crossing both the first surface and the second surface of the semiconductor lamina.
