Crystalline MoOx Thin-Films as Hole Transport Layers in DBP/C70 Based Organic Solar Cell

摘要

Transition Metal Oxides such as Molybdenum oxide (MoOx) have been intensively used as hole transport layers in different organic, inorganic and hybrid technologies, demonstrating also important improvements on the power conversion efficiency as well as on the stability of different types of solar cells. Among several different deposition methods available for fabrication of MoOx thin-films, reactive sputtering arises as an interesting alternative due to its full control over the deposition parameters such as the deposition power, reactive gas partial pressure and the deposition rate.
