- Title
Solar Cells: Over 14% Efficiency of Directly Sputtered Cu(In,Ga)Se<sub>2</sub> Absorbers without Postselenization by Post-Treatment of Alkali Metals (Adv. Energy Mater. 13/2017).

- Abstract
Cu(In,Ga)Se2 solar cells sputtered from a single quaternary target without post‐selenization yield efficiency of 14.1%, a record for using directly sputtering. The enhanced efficiency is achieved by sequential post‐treatments of Na and K, which improve the absorber quality due to effective passivation. This is reported in article number 1602571 by Chih‐Huang Lai and co‐workers.
