Synthesis of CuInSe2 thin films from electrodeposited Cu11In9 precursors by two-step annealing [PDF]

open access: yesJournal of Electrochemical Science and Engineering, 2014
In this study, copper indium selenide (CIS) films were synthesized from electrodeposited Cu-In-Se precursors by two-step annealing. The agglomeration phenomenon of the electrodeposited In layer usually occurred on the Cu surface.
