화학습식공정을 통한 칼코제나이드계 태양전지용 CuInS2 박막제조

Abstract

A solution-based process was suggested for preparing a CulnS2 thin film deposited on a glass substrate. which can be applied to the absorber of chalcogenide-type photovoltaics. Chemical bath deposition (CBD) was adopted with various deposition temperatures and time periods, and we found that they can cause different film thicknesses and band-gap energies of films prepared. We proved that the film prepared with specific condition of CBD (70℃ for 2h) was not only mechanically robust but also showed feasible absorption pattern for both visible light and near infra-red.
