[en] In this work we report the successful assembly and characterization of a TiO₂/In₂S₃-Sb₂S₃/CuSCN extremely thin absorber solar cell. Nanostructured TiO₂ deposited by screen printing on an ITO substrate was used as an n-type electrode. An ∼80 nm extremely thin layer of the system In₂S₃-Sb₂S₃ deposited by successive ionic layer adsorption and a reaction (silar) method was used as an absorber. The voids were filled with p-type CuSCN and the entire assembly was completed with a gold contact. The solar cell fabricated with this heterostructure showed an energy conversion efficiency of 4.9%, which is a promising result in the development of low cost and simple fabrication of solar cells.
