“…Since the rst report on the material by Uhlir 1 in 1956 NPSi fabrication techniques have demonstrated continuous advancement with regard to their ability to produce smaller pore sizes and higher pore aspect ratios. NPSi with precise pore morphology control shows promise as a versatile material due to its demonstrated potential application in optoelectronics, 2 sensors, 3,4 biological applications, 5 exible electronics 6 and photovoltaics, [7][8][9][10][11] where thin NPSi membranes are attractive for applications in nanoltration 12,13 and thermoelectrics. [14][15][16][17] Despite this potential, current methods of fabricating NPSi with large-area, monodisperse pore coverage are limited.…”

“…At the same time, the performance of silicon solar cells with PS layer is more than that of silicon solar cells with conventional ARC. Ag-induced chemical etching of multicrystalline silicon solar cells producing nanoporous "black silicon" (see handbook chapter "▶ Color of Porous Silicon") with low surface reflectance (<5 %) results in significant efficiency enhancement of 26 % (Shi et al 2013). Fabrication of nanoporous structure on screen-printed silicon solar cells using wet chemical etching by size-controlled silver nanoparticles demonstrates reflectance less than 5 % and 15.7 % efficiency (Dan et al 2013).…”

“…To be specific, the incoming short-wavelength light in silicon (Si) IP undergoes triple or more bounces before being reflected away, possessing one or more bounces than that in traditional upright pyramids [7][8][9]. Meanwhile, this inverted pyramid-structured Si will avoid severe recombination losses faced by the nanostructured black Si [10][11][12][13][14][15][16] because of its big and open structural characteristic.…”

Surface texturing is one of the most important techniques for improving the performance of photovoltaic (PV) device. As an appealing front texture, inverted pyramid (IP) has attracted lots of research interests due to its superior antireflection effect and structural characteristics. In this paper, we prepare high-uniform silicon (Si) IPs structures on a commercial monocrystalline silicon wafer with a standard size of 156 × 156 mm 2 employing the metal-assisted chemical etching (MACE) and alkali anisotropic etching technique. Combining the front IPs textures with the rear surface passivation of Al 2 O 3 /SiN x , we fabricate a novel Si IP-based passivated emitter and rear cell (PERC). Benefiting from the optical superiority of the optimized IPs and the improvement of electrical performance of the device, we achieve a high efficiency of 21.4% of the Si IP-based PERC, which is comparable with the average efficiency of the commercial PERC solar cells. The optimizing morphology of IP textures is the key to the improvement of the short circuit current I sc from 9.51 A to 9.63 A; meanwhile, simultaneous stack SiO 2 /SiN x passivation for the Si IP-based n + emitter and stack Al 2 O 3 /SiN x passivation for rear surface guarantees a high opencircuit voltage V oc of 0.677 V. The achievement of this high-performance PV device demonstrates a competitive texturing technique and a promising prospect for the mass production of the Si IP-based PERC.
