Polymer Solar Cells: Panchromatic Sequentially Cast Ternary Polymer Solar Cells (Adv. Mater. 4/2017)

To increase the range of light absorption in polymer solar cells, two absorber donor polymers (blue and red, respectively) are utilized. In article 1604603, H. Ade and co-workers mix these polymers separately with a fullerene acceptor (grey) and process them using a new deposition strategy to create sequentially cast ternary (SeCaT) polymer solar cells that exhibit a bilayer structure without an interlayer.
