    摘要: 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.
