Acceptor Y22 with an asymmetric hexacyclic A–DA′D–A structure achieved a high PCE of 15.4% and a high Jsc of 24.37 mA cm−2, which are among the best values reported for asymmetric acceptor based binary organic solar cells.

AbstractWe report on the improved performance of large-area organic solar cells and modules by integrating metal grids directly with the indium tin oxide (ITO), thereby reducing the series resistance contribution from the ITO. Devices with different areas (0.1, 7, and 36.4 cm2) were prepared to study the area-dependency of the organic solar cells based on pentacene and C60 heterojunctions. Modules were prepared in which four individual cells (7 cm2) were connected in series and parallel. For the series connected modules, VOC scales linearly with the number of cells while parallel connected modules exhibited multiplied current density as expected.
