Polymer Solar Cells: Matrix Organization and Merit Factor Evaluation as a Method to Address the Challenge of Finding a Polymer Material for Roll Coated Polymer Solar Cells (Adv. Energy Mater. 10/2015).

In article number 1402186, Eva Bundgaard and co‐workers present a large study via which a library of conjugated polymers is developed to identify lead candidates that are suitable for indium tin oxide (ITO)‐free, flexible polymer solar cells that are fully printed under ambient conditions. Based on several characteristics, 13 lead candidates are found, out of the 104 synthesized polymers. The variation in light absorption (color) of the 104 synthesized polymers is shown on the cover.
