Abstract

Abstract : The Cover Feature shows the double‐pulse electrodeposition of a CuGaS2 photovoltaic thin film on an FTO substrate. The chalcopyrite film is deposited by pulsing a −0.8 V vs. Ag/AgCl potential, depositing an impure wide bandgap ternary chalcogenide, followed by a −0.2 V Ag/AgCl potential to dissolve the CuS impurity phase. The CuGaS2 film is deposited in one step in an all‐elements‐contained aqueous solution, using Na2 S2 O3 as the sulfur source. Highly pure CuGaS2 films are deposited without copper sulfide impurities and without the need for KCN post‐treatment. More information can be found in the Communication by M. A. S. Andrade Jr. et al. on page 2998 in Issue 12, 2019 (DOI: 10.1002/celc.201900316 ).
