Abstract:In this paper, a thermodynamic analysis on current photovoltaics wsa given within the Shockley-Queisser model. Then the latest progresses of designing semiconductor nanowire arrays are introduced to achieve effective light trapping and reduced emission angle. Among them, non-uniform nanowire arrays with gradient shapes hold both advantages of ultralow emission angle and light trapping, therefore has attracted much research interest toward ultrahigh efficiency of solar energy conversion from visible to near-infrared wavelength.
