Room-temperature solution processed SnOx as an electron extraction layer for inverted organic solar cells with superior thermal stability

Abstract

Solution processed tin oxide (SnO_x) is used as an electron extraction interlayer in organic solar cells. As opposed to devices using TiO_x, cells based on SnO_x are stable even at elevated temperatures in the presence of moisture. Thus, by using SnO_x instead of TiO_x the requirements for a costly ultra-barrier encapsulation may be relaxed.
