Organic Solar Cells: Improvement of Transparent Metal Top Electrodes for Organic Solar Cells by Introducing a High Surface Energy Seed Layer (Adv. Energy Mater. 4/2013)



original image

The cover illustrates a flexible small molecule solar cell with three different semitransparent silverbased top electrodes using varying seed layers. With increasing surface energy of the seed layer, the wetting of subsequently deposited silver is significantly improved as indicated in the zoomed out SEM microscope images. For continuous and closed silver films, the transparency of the electrode, the optical field distribution inside the solar cell, and its power conversion efficiency are strongly increased. Further details can be found in the article by Sylvio Schubert and co-workers on page 438.
