Paper Abstract

MoO3 hole transportation layer was prepared by a novel spray coating method under low temperature for polymer solar cell. The physical phase of spray coated MoO3 thin film was demonstrated by X-ray diffraction. The surface morphology of solution processed MoO3 (s-MoO3) and thermally evaporated MoO3 (e-MoO3) was characterized by metallurgical microscope and atomic force microscopy. The PSC device based on s-MoO3 HTL shows better photo to electron conversion efficiency (PCE = 2.93%) performance than PEDOT:PSS based devices (PCE = 2.80%), and the high Jsc obtained in s-MoO3 based PSC device indicates that the transportation across the s-MoO3 layer is unhindered. Finally, the stability of PSC devices based on different HTLs has also been investigated.
