Due to intrinsic defects, zinc oxide nanoparticles may induce interfacial recombination when used as the electron extraction layer in an inverted polymer solar cell. On page 1333 , Franky So, John R. Reynolds, and co‐workers demonstrate that UV‐ozone treatment is an effective way to passivate defects in ZnO NPs and reduce interface recombination in a polymer solar cell. As a result, the power conversion efficiency of inverted PDTGTPD: PC 71 BM cells is improved to 8.1%.
