Texture etched Al-doped ZnO: a new material for enhanced light trapping in thin film solar cells
Oliver Kluth,A. Loffl,S. Wieder,C. Beneking,W. Appenzeller,Lothar Houben,Bernd Rech,Heribert Wagner,S. Hoffmann,Rainer Waser,J.A.A. Selvan,Herbert Keppner +11 more
TL;DR: In this article, the authors found that sputtered ZnO:Al films with an appropriate compact structure develop a surface texture during etching in diluted HCl with excellent optical and light trapping properties.
