The present invention includes a series of compounds, polymeric compounds used to make semiconductor and optoelectronic materials and devices, including thin film and bandgap materials for photovoltaic applications, including devices and systems for energy conversion and solar cells. It relates to a composition. In particular, the present invention relates to polymeric precursor compounds and precursor materials for making photovoltaic layers. The precursor compound may comprise repeat units {M A (ER) (ER)} and {M B (ER) (ER)}, where each M A is Cu, each M B is In or Ga, and each E is S, Se or Te, and each R is independently selected at each occurrence from alkyl, aryl, heteroaryl, alkenyl, amido, silyl, and inorganic and organic ligands. |
