Techniques for roll-to-roll manufacturing of flexible rectenna solar cells

Abstract

Rectenna solar cells (RSCs) are composed of arrays of antenna elements with nanoscale features and corresponding THZ-frequency diodes that convert incident radiation into electricity. Given that semiconductor fabrication facilities today have the capability of producing such devices, it may seem that, with ongoing efforts to improve nanoantenna device physics, RSCs should eventually be commercially available. So what's the problem?
