The performances of silicon solar cell with core–shell p-n junctions of micro-nano pillars fabricated by cesium chloride self-assembly and dry etching

Anti-reflection textured structures by wet etching and island lithography for surface-enhanced Raman spectroscopy

“…Using the process of island lithography involving the controlled growth of CsCl thin film into disordered islands in humidity environments, the random silicon nanopillars have been fabricated for the applications of solar cell [32,39,40]. The dimension of the nanopillars can be easily controlled by controlling the dimension of CsCl island and the time of dry etching [40]. Island lithography has also been used to fabricate some surface textures, such as clustered spheres on silicon substrate for the SERS application [28].…”

“…Also, because of its strong crystal compound, CsCl can be a good choice for a removable mask. Using the process of island lithography involving the controlled growth of CsCl thin film into disordered islands in humidity environments, the random silicon nanopillars have been fabricated for the applications of solar cell [32,39,40]. The dimension of the nanopillars can be easily controlled by controlling the dimension of CsCl island and the time of dry etching [40].…”

“…Smaller structures such as nanorods or nanopillars can be obtained through the metal-assisted chemical etching [35] or dry etching method [36][37][38] has several advantages, such as low cost and mass productive, and it has been extensively used. Some nanoparticles, such as silver [36], silicon carbide [37], silicon oxide [38], and cesium chloride (CsCl) [32,39,40], can collocate with dry etching as masks to fabricate nanopillars. Among the above nanoparticles, CsCl is an inorganic salt which has very strong water absorptivity, and CsCl thin film can form hemispheres in a humidity environment.…”

Fabrication of inverted pyramid structure by Cesium Chloride self-assembly lithography for silicon solar cell

“…The nanoislands were originally fabricated through CsCl self-assembly method, which allows evaporation of the thermal coating, facile formation involving water, and removal using water [18][19][20][21]. Titanium (Ti) template as etching masks against the anisotropy corrosion was formed by lift-off CsCl nanoislands.…”

Fabrication and doping of silicon micropillar arrays for solar light harvesting

“…By determining the short circuit current density (J SC ) and the open circuit potential (V OC ), the typical diode (in the dark) or solar cell (under illumination) characteristics and performance of doped pillar arrays can be determined. The improved performance of pillared surfaces over planar surfaces has been shown in numerous studies, for both solar cells [21,29,120] and photoelectrochemical (PEC) experiments. [1,2,20] In some cases, pillared surfaces have shown up to double the amount of current.…”
