Abstract

A simple and efficient method has been developed to eliminate the internal stress in molybdenum oxides by an ultraviolet ozone treatment. The results of X-ray photoelectron spectroscopy, ultraviolet photoelectron spectroscopy, and Raman spectroscopy indicate that oxygen vacancy was a determining factor of the compressive stress in MoO3, which can be released by ultraviolet ozone treatment. Based on this hole-transporting layer, the photovoltaic power conversion efficiency up to 3.91% was achieved, which is 22% higher than that without ultraviolet ozone treatment. And ultraviolet ozone treatment on MoO3 is a useful method to embellish the interface to enhance the ability of collecting hole of hole-transporting layer to improve the performance of OSC with MoO3 film as hole-transporting layer.
