摘要
PURPOSE: A method for manufacturing a silicon nano-wire/carbon-nano-tube/zinc oxide core/multi-shell nano composite and a solar cell including the nano composite are provided to vertically arrange the nano composite on a large-sized substrate. CONSTITUTION: A mono-crystalline silicon substrate undergoes ultraviolet/ozone treatment. The substrate is etched using an etching solution. The etching solution is based on a mixture of HF and AgNO_3. The etched substrate is immersed in a HNO_3 solution in order to eliminate silver dendrite from the substrate. A cleaning process and a drying process are implemented. A silicon substrate, on which silicon nano-wire is vertically arranged, is obtained. The silicon substrate is arranged in a thermal chemical vapor deposition apparatus, and carbon-nano-tube is deposited on the silicon nano-wire in order to obtain a silicon nano-wire/carbon-nano-tube core/shell nano composite.
