Abstract: A structure for increasing utilization rate of target is disclosed, which comprises: a magnetic base, capable of moving relative to a target in a reciprocating manner; and two magnetic conductors, disposed respectively at two motion limits with respect to the reciprocating range of the magnetic base. Thereby, when the magnetic base is moved to a position close to any one of magnetic conductors, the surface magnetic field intensity of the target that is caused by the magnetic base is reduced so that the ion bombardment happening at the two ends of the target will be eased off for increasing the utilization rate of the target.

Abstract: A solar cell having a reflective structure is provided, which includes a front contact, a P layer, an I layer, an N layer, and a back contact that are stacked together. The solar cell having the reflective structure is characterized in that the N layer is a layer of low refraction index, and a refraction index of the layer of low refraction index is lower than that of the I layer. Furthermore, the N layer may be a multi-layer structure consisting of several films in which films with low refraction indexes and films with high refraction indexes are stacked alternately. The film in contact with the I layer in the multi-layer structure is a film of low refraction index. A refraction index of the film of low refraction index is lower than that of the I layer.

Abstract: A guided mode resonance solar cell includes a solar cell body and a guided mode resonance unit. The solar cell body is used for converting optical energy into electrical energy. The guided mode resonance unit is formed on the solar cell body, and includes a grating structure and a waveguide structure. The grating structure includes multiple sub-wavelength light pillars. When a light emitted from a light source is incident onto the grating structure, a resonant of the light occurs in the grating structure to facilitate trapping the light in the waveguide structure and elongating an optical path length.
