As an alternative to poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) hole transporting layer (HTL) in low cost solution-processable polymer solar cells (PSCs), interests in p-type like metal oxides such as molybdenum oxide (MoO3), vanadium oxide(V2O5) and nickel oxide (NiO) has been increased. In particular, MoO3 is one of the promising materials since it is known as a non-toxic material and has a well-matched energy level with P3HT to induce efficient hole transport to transparent electrode. In this study, we demonstrate bulk-heterojunction PSCs with MoO3 produced by brush painting, which is compatible with roll-to-roll based manufacturing system. We will discuss structural, electrical, and optical characteristics of brush painted MoO3 and their effect on performance of PSCs will be discussed. |
