摘要： Methods of forming two-dimensional nanopatterns are provided. The method may comprise periodically contacting a vibrating tool comprising a patterned grating edge with a substrate along a first direction in a grating-vibrational indentation patterning process. The patterned grating edge defines a plurality of rows and a plurality of interspersed troughs. The periodic contacting creates a two dimensional array of discontinuous voids in a single-stroke across the surface of the substrate. In other aspects, a microfluidic device for selective arrangement of a microspecies or nanospecies is provided, that includes a substrate comprising a surface defining a two-dimensional pattern of microvoids or nanovoids. In yet other aspects, the present disclosure provides a method for selective arrangement of a microspecies or nanospecies on a substrate.

摘要： In various aspects, the present disclosure provides photodetector devices that may be provided in arrays. The photodetector includes a first electrode, a second electrode, and a photoactive layer assembly disposed therebetween. The photoactive layer assembly comprises a first charge transport layer, a second charge transport layer, and an amorphous silicon (a-Si) material substantially free of doping and being substantially free of doping disposed between the first charge transport layer and the second charge transport layer. The photodetector device transmits light in a predetermined range of wavelengths and is capable of generating detectable photocurrent when light having a light intensity of less than or equal to about 50 Lux is directed towards the photodetector device.

摘要： An organic photovoltaic cell comprises a first electrode, a second electrode, an active layer comprising at least one donor material and at least one acceptor material, positioned between the first electrode and the second electrode, an outcoupling layer positioned on a surface of the first electrode such that the first electrode is positioned between the outcoupling layer and the active layer, and an anti-reflective coating positioned over a surface of the second electrode such that the second electrode is positioned between the anti-reflective coating and the active layer, wherein the organic photovoltaic cell is at least semi-transparent to at least one wavelength range. A method of fabricating an organic device is also described.
