The image depicts indium tin oxide (ITO)‐free polymer solar cells, prepared by ink jet printing a composite front electrode comprising silver grid lines and a semitransparent PEDOT:PSS conductor. On page 103 , Y. Galagan et al. demonstrate the effect of grid‐line density on the performance of these current‐collecting grids for ITO‐free polymer solar cells. A careful modeling study enabling the identification of the most rational grid structure is presented. Both optical and light beam‐induced current mapping of the devices are used to support the power‐loss model and to follow the evolution of the performance over time.
