Comparative degradation analysis of V₂O₅, MoO₃ and their stacks as hole transport layers in high-efficiency inverted polymer solar cells

Abstract

The use of V₂O₅, MoO₃ and their stacks as the buffer anode in organic solar cells greatly improves the lifetime of the photovoltaic devices, with a remaining PCE of over 50% of the initial PCE after 19 600 h (about 2 years).
