Abstract: Provided are an apparatus for producing inorganic powder, and a method of producing inorganic powder by using such. The apparatus includes a vaporization part where a condensed-phase precursor is vaporized to obtain a gas-phase precursor, a partial precipitation part where the gas-phase precursor obtained in the vaporization part is partially precipitated to a condensed phase, and a reaction part where the gas-phase precursor remaining after being partially precipitated to a condensed phase in the partial precipitation part reacts with a reaction gas to obtain inorganic powder. An equilibrium vapor pressure of the gas-phase precursor in the partial precipitation part is lower than a vapor pressure of the gas-phase precursor obtained in the vaporization part, and an equilibrium vapor pressure of the precursor in the reaction part is equal to or higher than a vapor pressure of the gas-phase precursor partially precipitated to a condensed phase in the partial precipitation part.

Abstract: A method of manufacturing a carrier-selective contact junction silicon solar cell includes: preparing a conductive silicon substrate; forming a first passivation layer and a second passivation layer on and under the conductive silicon substrate, respectively; forming an electron-selective contact layer under the second passivation layer; forming a hole-selective contact layer on the first passivation layer; forming an upper transparent electrode on the hole-selective contact layer; forming an upper metal electrode on the upper transparent electrode; and forming a lower metal electrode under the electron-selective contact layer. In forming the hole-selective contact layer, a sandwich-structured multilayer film is formed by depositing a copper iodide thin film on a top surface and a bottom surface of an iodine thin film, and a single-film copper iodide thin film is formed by low-temperature annealing the sandwich-structured multilayer film.
