摘要：

Nanowires (NWs) solar cells are expected to outperform the thin-film counterparts in terms of optical absorptance. In this theoretical study we optimize the geometry of vertical crystalline-amorphous silicon core-shell NW arrays on doped ZnO:Al (AZO)-Glass substrate by means of 3-D optical simulations in order to maximize the photon absorption. The optimized geometry is investigated by means of 3-D TCAD numerical simulation in order to calculate the ultimate efficiency and the main figures of merit by taking into account recombination losses. We show that optimize - long crystalline amorphous silicon core-shell (c-Si/a-Si/AZO/Glass) NWs can reach photogenerated current up to 22.94 mA/cm(2) (above 45% larger than that of the planar counterpart with the same amount of absorbing material) and conversion efficiency of 13.95%.
