    摘要： An active plasmon sensor comprising a single crystalline semiconductor CdS nano-slab atop a silver surface separated by a magnesium fluoride (MgF2) gap layer. The surface plasmon effect localizes the electromagnetic field at the interface between the metal and semiconductor, allowing both the device's physical size and mode confinement to shrink down to the nanometer scale in a dimension perpendicular to the metal surface.

    摘要： This invention improves the efficiency of non-optimal solar cell materials, enabling them to achieve the same efficiency as optimal materials. The invention describes a method of improving the emission and absorption properties of a generic photovoltaic cell using feedback reflectors and/or filters, increasing the open circuit voltage of the cell, and thus the overall efficiency. Specific examples of single junction photovoltaics are detailed, but not limited to. Particularly, semiconducting solar cells in either single- or multi-junction formats are described. The invention can be applied to any functioning solar cell to increase the efficiency, while describing the maximal efficiency available using thermodynamic identities. Other examples are included, such as organic photovoltaic, nanostractured photovoltaic devices, and non-planar geometries. The invention thus enables using non-optimal photovoltaic materials to achieve similar efficiency results as optimal ones, regardless of the designed structure or material used.
