Abstract
This invention relates to methods and articles using compounds, polymeric compounds, and compositions for semiconductor and optoelectronic materials and devices including thin film and band gap materials. This invention provides a range of compounds, polymeric compounds, compositions, materials and methods directed ultimately toward photovoltaic applications, transparent conductive materials, as well as devices and systems for energy conversion, including solar cells. In particular, this invention relates to polymeric precursor compounds and precursor materials for preparing photovoltaic layers. A compound may contain repeating units {MB(ER)(ER)} and {MA(ER)(ER)}, wherein MA is a combination of Cu and Ag, each MB is In or Ga, each E is S, Se, or Te, and each R is independently selected, for each occurrence, from alkyl, aryl, heteroaryl, alkenyl, amido, silyl, and inorganic and organic ligands.
