Arrays of parallel connected coaxial muitiwall-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 1.5G), the short-circuit current of our carbon-nanotube enhanced solar cell is ∼25% higher than that of the planar cell. © 2009 WILEY-VCH Verlag GmbH & Co.
