    摘要: Photovoltaic cells (10) and methods for manufacturing photovoltaic cells (10). An example photovoltaic cell (10) may include an electron conductor (14), a hole conductor (22) and an active region (20) situated therebetween. The electron conductor (14) may include a nanowire array (16) and a sheath (18) disposed over the nanowire array (16). The nanowire array (16) may include a material having an electron mobility that is greater than the electron mobility of the sheath (18). The sheath (18) may have a density of states that is greater than the density of states of the nanowire array (16).

    摘要: Lateral collection photovoltaic (LCP) structures based on micro- and nano-collecting elements are used to collect photogenerated carriers, wherein the position of the collecting elements is determined by pattern transfer of an alternating depth trench pattern into a material to undergo solid phase crystallization: one depth corresponds to the elements of an electrode and the other depth corresponds to the elements of the counter-electrode. At least one of the metal electrode collecting elements can serve to enhance solid phase crystallization of the surrounding material in which the trenches were formed.
