Cover Picture: phys. stat. sol. (b) 245/9

This Special Issue of physica status solidi (b) contains arti‐cles that are taken from a Festschrift entitled “Solar Energetics – From Photovoltaics to Water Splitting” which is dedicated to Professor Helmut Tributsch (Hahn‐Meitner‐Institut Berlin, Germany) on the occasion of his retirement. The cover picture illustrates a new, catalytic metal‐substrate/solar‐cell structure for the photo(electrochemical) conversion of sunlight into chemical energy (H 2 ) by water‐splitting. It is a scheme of a prototype solar cell consisting of a Cu(In,Ga)Se 2 absorber, a CdS buffer layer, and a TiO 2 :Nb TCO layer. For details see the article by Bernhard Neumann et al. (pp. 1849–1857).
