SILICON SOLAR CELL AND FABRICATION METHOD THEREOF

摘要

The object of the present invention is to provide a method for fabricating a silicon solar cell according to one aspect of the present application. In a method for fabricating a silicon solar cell, first, a silicon substrate doped in a first conductive type is prepared. An emitter layer of a second conductive type opposite to the first conductive type is formed on the silicon substrate. A light absorption surface area of the emitter layer is increased by processing the emitter layer. A zinc oxide seed layer is formed on the processed emitter layer using a hydrothermal process. A zinc oxide reflection prevention layer having a nanorod shape is grown from the zinc oxide seed layer using the hydrothermal process.
