JVST A: Flexible CIGS Solar Cells using Atomic layer Deposition

I remember testing the laboratory-scale rotary spatial-ALD reactor from this innovative at TNO in Eindhoven team lead by Paul Poodt and Fred Roozeboom some years ago and was very impressed then that it was possibly to grow highly conformal films in high aspect ratio structures so fats by ALD. Now their technology has evolved much further - here "Atmospheric spatial atomic layer deposition of ZnOS buffer layers for flexible Cu(In,Ga)Se2 solar cells"
