摘要

MoOx HTL exhibits good applicability while showing excellent performance in both ternary and all-polymer systems.

Abstract

The hole transport layer (HTL) affects the device performance and stability of organic solar cells. In this work

a stable molybdenum oxide (MoO

) hole transport layer with low cost was prepared by adjusting the state of the precursor solution with an alcoholic solution of molybdenum acetylacetonate through an oxidant. The MoO

transport layer has good transmittance with a work function of 5.07 eV and higher surface energy. The PM6:Y6 devices using MoO

HTL achieve a high efficiency of 16.8%. MoO

HTL exhibits good applicability with excellent performance in both ternary and all-polymer systems. Air storage stability

of the all-polymer device using MoO

HTL was over 600 h

much higher than 70 h of the PEDOT:PSS-based device

and its thermal stability at 85 °C and operational stability under light show better stability than that of the PEDOT:PSS hole transport layer. This work provides a facile and low-cost method to fabricate HTL for organic solar cells

which is beneficial to improve their efficiency and stability.
