In this feature article, we review the recent achievements on SiNWs for advanced energy conversion and storage applications including. Silicon nanowirePhotovoltaicsPhotocatalysisThermoelectricsLithium-ion batterySupercapacitorSilicon is currently the most dominant functional material for commercial electronic applications due to the following beneficial features: (1) the second most abundant element on Earth; (2) high stability and non-toxicity; (3) high carrier mobility; and (4) well-established fabrication technique. In recent years, low-dimensional silicon nanostructures have been extensively studied as nanoscale building blocks for high-performance electronic and photonic devices in light of their attractive physical and chemical properties that are different from those of bulk silicon,,,,,,,,,,,,,,,,,. Among low-dimensional silicon nanostructures, silicon nanowires (SiNWs) possess unique structural, electrical, optical, and thermoelectric properties. SiNWs are thus regarded the most attractive candidate for various device applications such as high-performance transistors,,,,,, ultrahigh sensitivity chemical/biological sensors,,,,,,, cost-efficient photovoltaic devices,,,,,,, low-cost thermoelectric devices,, and high-capacity lithium-ion rechargeable batteries,,.To meet the world's growing energy demand and fast-growing market for portable electronic devices, such as cell phones and laptops, significant advances in energy conversion and storage technologies are urgently neede. The properties of SiNWs strongly depend on their preparation methods, ; therefore the fabrication methods of SiNWs with controlled properties are extremely important, and the research efforts in the field have primarily focused on the fabrication of SiNWs for technological applications.
