Study the Effect of Silicon Nanowire Length on Characteristics of Silicon Nanowire Based Solar Cells by Using Impedance Spectroscopy

Silicon nanowire (SiNW) arrays were produced by electroless method on polycrystalline Si substrate, in HF/ AgNO3 solution. Although the monocrystalline silicon wafer is commonly utilized as a perfect substrate, polycrystalline silicon as a low cost substrate was used in this work for photovoltaic applications. In order to study the influence of etching time (which affects the SiNWs length) on d...

Silicon nanowire solar cells

Silicon nanowire-based solar cells on metal foil are described. The key benefits of such devices are discussed, followed by optical reflectance, current-voltage, and external quantum efficiency data for a cell design employing a thin amorphous silicon layer deposited on the nanowire array to form the p-n junction. A promising current density of 1.6 mA /cm2 for 1.8 cm2 cells was obtained, and a ...

Crystalline Silicon Solar Cells

Front page headlines in the New York Times and the Wall Street Journal in 1954 heralded to the world the demonstration of the first reasonably efficient solar cells, an event made possible by the rapid development of crystalline silicon technology for miniaturised electronics. Since that time, the majority of solar cells fabricated to date have been based on silicon in monocrystalline or large-...
