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

Abstract

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