Cu‐Rich Precursors Improve Kesterite Solar Cells. Issue 2 (19th September 2013) - Mousel, Marina
Abstract A precursor‐annealing process based on a Cu‐rich precursor that has a maximum power conversion efficiency of 7.5% for pure selenide kesterite cells is presented. The Cu‐rich step is beneficial for the transport properties. Nanometer‐sized domains of ZnSe are found in all films.
