The structural, electrical, and optical properties of Al2O3:ZnO(1:x) nanolaminates synthesized by atomic layer deposition are evaluated as a function of the relative number of cycles x. Al2O3:ZnO(1:20) nanolaminates exhibit a seven-fold increase in electrical conductivity compared with neat ZnO films, which is attributed to changes in the crystal structure of the films and doping effects. Efficient poly(3-hexylthiophene) (P3HT):phenyl-C61 -butyric acid methyl ester (PCBM) poly- mer-based inverted solar cells utilizing Al2O3:ZnO(1:20) nanolaminate electron-selective electrodes are demonstrated.
