Abstract
Thin-film solar cells of the CIGS-type use two integrally formed buffer layers, a first ALD Zn(O,S) buffer layer on top of the CIGS-layer and a second ALD ZnO-buffer layer on top of the first buffer layer. Both buffer layers are deposited in the same process step using ALD (atom layer deposition). The technology also relates to a method of producing the cell and a process line for manufacturing of the cell structure.
