Abstract
A method and apparatus for forming a solar cell structure. A first wafer and a second wafer are positioned relative to each other such that first nanotubes on the first wafer are opposite to second nanotubes on the second wafer. The first nanotubes are connected to the second nanotubes. The first wafer is connected to the second wafer to form the solar cell structure.
Claims18
A method for forming a solar cell structure, the method comprising:
- positioning a first wafer and a second wafer relative to each other such that first nanotubes on the first wafer are opposite to second nanotubes on the second wafer;
- and
- connecting the first nanotubes to the second nanotubes, wherein the first wafer is connected to the second wafer to form the solar cell structure, wherein the first nanotubes extend in a direction substantially perpendicular to a first surface of the first wafer and the second nanotubes extend in a direction substantially perpendicular to a second surface of the second wafer.
A solar cell structure comprising:
- a first wafer;
- a second wafer;
- first nanotubes formed on the first wafer;
- and
- second nanotubes formed on the second wafer, wherein the first wafer and the second wafer are positioned relative to each other such that the first nanotubes are opposite the second nanotubes, and wherein the first nanotubes and the second nanotubes are connected to each other, and wherein the first nanotubes extend in a direction substantially perpendicular to a first surface of the first wafer and the second nanotubes extend in a direction substantially perpendicular to a second surface of the second wafer.

A method for forming a structure, the method comprising:
- positioning a first wafer and a second wafer relative to each other such that first nanotubes on the first wafer are opposite to second nanotubes on the second wafer;
- and
- connecting the first nanotubes to the second nanotubes, wherein the first wafer is connected to the second wafer to form the structure, wherein connecting is performed by forming a bond based on van der Waals forces between the first nanotubes and the second nanotubes.
