The present issue of pss‐Rapid Research Letters continues our Focus on Photovoltaics started in August 2008 (Vol. 2, Issue 4). Once again authors from leading European institutes in the field of solar cell research aim to achieve record efficiencies and explore new frontiers in a variety of materials systems and device concepts, ranging from crystalline silicon technology to fullerenes and organic materials. The cover picture relates to the Letter by Robert Bock et al. on page 248 ff. On the background of the cross‐sectional scanning electron microscopy (SEM) image of a screen‐printed Al‐p + Si emitter, a back‐junction n‐type Si solar cell is shown schematically (top left). The bottom‐left SEM image is a tilted plan‐view of the Al‐p + Si surface after the residual Al paste and the Al–Si eutectic have been removed. The top right image shows the corresponding cross‐section of the emitter overlaid by the electron beam induced current signal (blue) with the p–n junction region at a depth of 8 μm. The bottom right graph depicts the measured inverse effective lifetime as a function of the excess carrier density.
