Abstract

We report efficient and stable polymer solar cells (PSCs) based on poly(3-hexylthiophene) and various fullerene derivatives using solution processed, cost effective molybdenum oxide (s-MoOx) as an anode interfacial layer. The chemical structure of the obtained s-MoOx was characterized by FTIR and XPS. The s-MoOx layer exhibits high light transmittance and effective hole collection properties. The PSCs with the s-MoOx anode buffer layer show enhanced performance in comparison with PEDOT:PSS modified devices. The power conversion efficiency of the PSC based on P3HT:IC70BA with the s-MoOx anode buffer layer reached 6.57% under an illumination of AM1.5G at 100 mW cm−2. In addition, compared with PEDOT:PSS modified devices, PSCs with the s-MoOx anode buffer layer exhibit a much superior stability and longer lifetime.
