We report the development of Cd-free buffers by atomic layer deposition for chalcopyrite-based solar cells. Zn(O,S) buffer layers were prepared by atomic layer deposition on sequentially grown Cu(In,Ga)(Se,S)2 absorbers from Bosch Solar CISTech GmbH. An externally certified efficiency of 16.1% together with an open circuit voltage of 612mV were achieved on laboratory scale devices. Stability tests show that the behavior of the ALD-Zn(O,S)-buffered devices can be characterized weitereas stable...We report the development of Cd-free buffers by atomic layer deposition for chalcopyrite-based solar cells.
