“…In this paper, using hybrid structures showed better performance (lower reflectance) than single structure using the same etching method 16 , 21 . The results of using hybrid structures indicated that reflectance kept low and stable among 300 nm~1000 nm but that of using single structure in other may showed that reflectance increased in small wavelength 2 , 69 – 71 .…”

Black silicon fabrication and manipulation have been well reported by institutes around the world and are quite useful for solar absorption and photovoltaic conversion. In this study, silicon micro-nano hybrid structures were fabricated, and the morphologies of the hybrid structures were analyzed. This paper studied nanostructures formed on tips, pits and a flat surface using a dry etching method and a wet etching method. In terms of nanostructure morphology, nanostructures etched by the wet etching method (13 μm) were taller than those etched by the dry etching method (1 μm), but the wet etched morphology was less organized. After the nanostructures were grown, six samples with nano sturctures and three samples with micro sturctures were measured by a photometer for reflectivity testing. The nine samples were compared and analyzed using the integral of reflectivity and solar emissivity at the earth’s surface. The results show that the nanostructures grown on a tip surface using the wet etching method had the minimum reflectivity in the wavelength range of 300 nm–1100 nm, in consideration of the forbidden energy gap of silicon.

“…This approach becomes most effective outside on a clear day at higher temperatures, which are the same conditions typically describing many of the geographical sites best-suited for the production of concentrating solar power [4][5][6]. As such, we have begun to apply this approach to concentrated photovoltaics (CPV) [7] and solar thermophotovoltaics (TPV) [8][9][10].…”

“…Designing materials on the nanoscale can have a profound impact on how optical energy flows through those materials, which can in turn dramatically improve the performance of nanostructured materials for energy-related applications including solar and (solar)thermophotovoltaic energy conversion [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] , radiative cooling [18][19][20][21][22][23] , incandescent lighting [24][25][26][27] , among others. Multilayer planar nanomaterials, stacks of flat materials with nanoscale thickness, have emerged as promising candidates for such applications because they present highly tunable optical and thermal emission properties and are relatively easy to fabricate.…”

<div>Multilayer nanostructures represent an important class of materials with tunable optical and thermal radiative properties that can be leveraged for a wide range of energy applications. We present a theoretical framework for optimizing the geometry of such structures that utilizes gradients of various objective functions that are enabled through analytic differentiation of the transfer matrix equations. We demonstrate the usefulness of this method by applying it to the optimization of structures for incandescent light sources, and the global optimization of anti-reflective solar cell coatings.</div>
