    摘要： This invention is related to novel perylene diester derivatives represented by the general formula (I) or general formula (II) as described herein. The derivatives are useful in various applications, such as luminescent dyes for optical light collection systems, fluorescence-based solar collectors, fluorescence-activated displays, and/or single-molecule spectroscopy. The invention also relates to a luminescent medium, such as a luminescent film, that can significantly enhance the solar harvesting efficiency of thin film CdS/CdTe or CIGS solar cells. The luminescent medium comprises an optically transparent polymer matrix and at least one luminescent dye that comprises a perylene diester derivative. Over 16% of an efficiency enhancement to a CdS/CdTe solar cell and over 12% of an efficiency enhancement to a CIGS solar cell can be achieved.

    摘要： Described herein are optical devices comprising a photorefractive layer and at least two inert layers, such that the photorefractive layer is sandwiched between the two inert layers. The photorefractive layer may include a photorefractive composition that is photorefractive upon irradiation by a laser beam. In some embodiments, the photorefractive composition is formulated such that a grating that is irradiated into the photorefractive composition can be read out of the photorefractive composition without applying an external bias voltage. Furthermore, a grating that is written into the composition may be controlled using thermal treatment.

    摘要： A photorefractive device (100) and method of manufacture are disclosed. The device (100) comprises a layered structure, in which one or more chromophore-doped polymer layers (110) are interposed between a photorefractive material (106) and one or more electrode layers (104). The layered structure can also be interposed between a plurality of substrates (102). In some embodiments, the device (100) exhibits a decreased decay time when applying the biased voltage. Concurrently, the device (100) of the present disclosure utilizes approximately half the bias voltage, advantageously resulting in a longer device life time.
