“…The nanostructure was etched on the material, and the absorptivity reached 95% at the band of 400 nm to 1100 nm. In 2019, I. Putra et al [ 51 ] used alkaline etching to form tiny pyramidal structures on the surface. Micro-pores were formed in the micro-pyramid structure by the silver ion etching solution.…”

“…The DWS MC-Si solar cell filling factor was 80.07%, and the conversion efficiency was 19.07%. In 2019, I. Putra et al [ 51 ] made a B-Si solar cell by performing a silver-assisted chemical etching of the micro pyramid on a silicon wafer to form a finer nanocolumn structure on the micro pyramid. The increase in the formation time of Si nanopores led to a significant increase in photoluminescence properties.…”

Since black silicon was discovered by coincidence, the special material was explored for many amazing material characteristics in optical, surface topography, and so on. Because of the material property, black silicon is applied in many spheres of a photodetector, photovoltaic cell, photo-electrocatalysis, antibacterial surfaces, and sensors. With the development of fabrication technology, black silicon has expanded in more and more applications and has become a research hotspot. Herein, this review systematically summarizes the fabricating method of black silicon, including nanosecond or femtosecond laser irradiation, metal-assisted chemical etching (MACE), reactive ion etching (RIE), wet chemical etching, electrochemical method, and plasma immersion ion implantation (PIII) methods. In addition, this review focuses on the progress in multiple black silicon applications in the past 10 years. Finally, the prospect of black silicon fabricating and various applications are outlined.

“…Optoelectronic devices rely heavily on silicon (Si)-based materials owing to their high performance, low cost, earth abundance and convenient compatibility with complementary metal-oxide semiconductor (CMOS) technologies [ 1 ]. Recently, the surface topography of silicon wafers patterned with nano and microstructures of various shapes such as wires, needles, cones or pyramids demonstrated high potential for photodetector [ 2 ], photovoltaic [ 3 , 4 , 5 ] and sensor [ 6 ] applications. It is well known that the patterning process is the key factor leading to interesting optical properties and electrical characteristics [ 7 , 8 ].…”

In this work, we report the development of self-powered photodetectors that integrate silicon nanoholes (SiNHs) and four different types of metal nanowires (AgNWs, AuNWs, NiNWs, PtNWs) applied on the SiNHs’ surface using the solution processing method. The effectiveness of the proposed architectures is evidenced through extensive experimental and simulation analysis. The AgNWs/SiNHs device showed the highest photo-to-dark current ratio of 2.1 × 10−4, responsivity of 30 mA/W and detectivity of 2 × 1011 Jones along with the lowest noise equivalent power (NEP) parameter of 2.4 × 10−12 WHz−1/2 in the blue light region. Compared to the bare SiNHs device, the AuNWs/SiNHs device had significantly enhanced responsivity up to 15 mA/W, especially in the red and near-infrared spectral region. Intensity-modulated photovoltage spectroscopy (IMVS) measurements revealed that the AgNWs/SiNHs device generated the longest charge carrier lifetime at 470 nm, whereas the AuNWs/SiNHs showed the slowest recombination rate at 627 nm. Furthermore, numerical simulation confirmed the local field enhancement effects at the MeNWs and SiNHs interface. The study demonstrates a cost-efficient and scalable strategy to combine the superior light harvesting properties of SiNHs with the plasmonic absorption of metallic nanowires (MeNWs) towards enhanced sensitivity and spectral-selective photodetection induced by the local surface plasmon resonance effects.

“…For photovoltaic applications, the efficient way for trapping the visible lights within photoactive regions turned out to be essential for boosting the cell efficiency [18][19][20]. In such a requirement, the light-absorption characteristics essentially required the broadband and polarization-angle insensitive capabilities.…”

Metamaterial absorber with the unexpected capability for harvesting electromagnetic energy has been regarded as a potential route for various applications, including chemical/biological sensing, cloaking and photovoltaic applications. In this study, we presented the simple absorber design made with Al/SiO2/Al sandwich structures through the involvement of hybrid dual-resonators that could allow the wideband light absorption covered from 450 nm to 600 nm with average absorptivity above 95%. Examinations of excited electric field, magnetic field and total magnitude of electric field in three-dimensional space at resonances were performed to clarify the origin of resonant behaviors. In addition, an equivalent inductance–capacitance circuit model was proposed that could qualitatively explore the geometry-dependent absorption characteristics by modulating the constitutive parameters of hybrid resonators. As a result, the designed light absorber might enable to be practically applied for various optical-management and photovoltaic applications, and even offered the tunability for other desired frequency regions.
