Thin film photovoltaic structure
First Claim
1. A photovoltaic device, comprising:
- an insulator structure;
an exfoliation layer; and
a conductive layer integral to the exfoliation layer and proximate to the insulator structure; and
a bond bonding the insulator structure to the conductive layer and the exfoliation layer,wherein the exfoliation layer comprises a substantially single-crystal exfoliation layer of a substantially single-crystal donor semiconductor wafer.

Abstract
Photovoltaic devices include an insulator structure bonded to an exfoliation layer, preferably of a substantially single-crystal donor semiconductor wafer, and at least one photovoltaic device layer, such as a conductive layer. In a preferred embodiment, a device may include a conductive layer adjacent to the insulator substrate and integral to the exfoliation layer, near the side that faces the insulator substrate, such as between the insulator substrate and the exfoliation layer. In a further preferred embodiment, a device may include a plurality of photovoltaic device layers distal to the insulator substrate and in or on the exfoliation layer, preferably having been epitaxially grown on the exfoliation layer after the exfoliation layer has been anodically bonded to the insulator substrate by means of electrolysis.
