Abstract

This paper presents a new nanofiber photovoltaic cell with ITO/ZnO/ITO concentric core designed to have high efficiency of solar energy conversion. The high energy bandgap of ZnO relative to ITO creates quantum wells for effective charge transfer of photogenerated carries from the ZnO active region, and the higher refractive index of the ZnO relative to the ITO enables solar radiation, incident on the ITO inner and outer cores, to couple to the ZnO resulting in effective separation of the optical signal path and the drift current. At the highest fill factor of 0.941, the proposed fiber produces 0.654V as an open-circuit voltage with fiber length of 1mm; where the solar cell could operate at maximum power point of P_mp =0.24mW at V_mp =0.5722V and I_mp =0.0.415mA. The cell voltage and current are dependent on fiber length and area where the highest open-circuit voltage recorded at 0.9317V and the highest shortcircuits current recorded at 0.4379A for fiber length of 1μm with power of 0.408W.
