Thermal co-evaporated MoOx:Au thin films and its application as anode modifier in perovskite solar cells

Molybdenum oxide (MoOx) has been used as a suitable interfacial modifier for emergent solar cells. However, the relatively low electrical conductivity of such material requires a thickness less than 10 nm of MoOx, which may lead to an uncovered surface and reduce the effect of interfacial modification. In this work, MoO3 and Au powder were co-evaporated and MoOx:Au composite coatings with a thickness of 10–20 nm were obtained. They are highly...
