Arrays of Parallel Connected Coaxial Multiwall‐Carbon‐ Nanotube–Amorphous‐Silicon Solar Cells

Abstract

Arrays of parallel connected coaxial multiwall-carbon-nanotube–amorphous-silicon solar cells are fabricated. In this configuration, orthogonalization of the directions of light absorption and charge-carrier collection is realized. Under simulated solar illumination (AM 1.5 G), the short-circuit current of our carbon-nanotube enhanced solar cell is ∼25% higher than that of the planar cell.
