Globally, focus continues to be on how to generate energy from renewable sources. This is still a challenge for policy makers. Besides, storage of electrical energy remains a challenge today. With silicon nanowires, these challenges have been addressed. Using silicon nanowires, researchers have developed solar cells. The suitability of silicon nanowires in this area is that they allow for production of flexible solar cells at a low cost. Similarly, the efficiency at which this is achieved makes the technology very competitive in the energy production. In addition, silicon nanowires are critical in energy production and storage in that they can be used in improving the capacity of li-ion batteries when used as anodes.

Silicon nanowires present a quasi one-dimensional model with a thickness of not more than 100 nm. Such an occurrence brings about an outsized surface to volume ratio. Attributable to this incident, the SiNWs offer exploitation means in numerous ways as regards electronic devices. The nanowires make available an exceptional alternative for the definitive silicon insulator semiconductor devices, otherwise denoted as MIS. On the other hand, the same quality moreover permits implementing mechanism conceptions that bring about some unfortunate traits in a conservative planar arrangement. As a result, the “junction less” transistors along with the tunnel field effect system of transistors sketch out the outstanding cases in point. Besides, new styles of functionalities may be utilized by formulating the appliances in a reconfigurable manner. As regarding sensing devices, the diminutive capacity permits the helpful control of the potential of the nanowire, therefore making the process extremely susceptible exclusively for chemical sensing in addition to bio-sensing. Nevertheless, the field of power invention and storage gains from the operations of the quasi 1D configuration. In the formulation of the solar cells, SiNWs permit to more competently amass the inward bound solar emission while in Li-ion settings the constitution consents to volume increase.
The negative impact of the structures outlines the fact that the thermal conductivity of the entailed processes reduces when the breadth condenses. As a result, the desired outcomes may not be wholly achieved for the reason that the SiNWs formations vigorously transform to correspond to the altered formation. Furthermore, some better materials exist. Due to this occurrence, silicon might not be the most excellent choice of material as others have better and improved qualities. Outsized quantities of performances subsist to manufacture silicon nanowires, plus they can categorize into bottom-up along with top-down manufacture practices. As regards the top-down production, lithography systems characterize the fictitious arrangement that transfers obliquely from the photo-resist mode to the substrate approach using etching or a comparable system of configuring the already obtainable substance. With relation to the bottom-up procedure, the substance and objects add to the existing substrate through a discrete and self-organized approach.
