摘要：
Radial p-n junction nanowire (NW) solar cells with high densities of CdTe NWs coated with indium tin oxide (ITO)/ZnO/CdS triple shells were grown with excellent heterointerfaces. The optical reflectance of the devices was lower than for equivalent planar films by a factor of 100. The best efficiency for the NW solar cells was eta = 2.49%, with current transport being dominated by recombination, and the conversion efficiencies being limited by a back contact barrier (phi(B) = 0.52 eV) and low shunt resistances (R-SH < 500 Omega.cm(2)).
