• We report a p-n heterojunction solid-state solar cell completely fabricated by simple and tunable solution-based processing. The solar cell comprised of p-type CdTe that was electrochemically deposited onto hydrothermally synthesized vertically oriented arrays of n-type rutile TiO2 nanowire arrays (RNWAs), which were grown on fluorine doped tin oxide (FTO)-coated transparent conductive glass substrates. Morphological studies revealed the TiO2 nanowires to be completely infiltrated by the CdTe. The solid-state solar cell exhibited an open circuit voltage of 0.6 V, short-circuit current of 3.57 mAcm-2, a fill factor of 44 % and a power conversion efficiency of 0.96%.
