## Abstract

A method for constructing a solar rectenna array by growing carbon nanotube antennas between lines of metal, and subsequently applying a bias voltage on the carbon nanotube antennas to convert the diodes on the tips of the carbon nanotube antennas from metal oxide carbon diodes to geometric diodes. Techniques for preserving the converted diodes by adding additional oxide are also described.
