Abstract
A simple manufacturing method is provided for the fabrication of the IV-VI group of semiconductor films on inexpensive substrates for highly efficient tandem or multi junction solar cells and a variety of other electronic devices such as transistors and LEDs. Specifically, the method includes depositing a textured oxide buffer on a substrate; depositing a metal-inorganic film from a eutectic alloy on the buffer layer, the metal being a component of a IV-VI compound; and forming a layer on the metal-inorganic film on which an additional element from the IV-VI compound is added, forming a IV-VI layer on a semiconductor device. The films comprising tin sulfides—SnS (tin sulphide), SnS, and SnS—are grown on inexpensive substrates, such as glass or flexible plastic, at low temperature, allowing for R2R (roll-to-roll) processing.
