Formamidinium lead iodide perovskite photovoltaics with MoS₂ quantum dots.

ABSTRACT: We present the formation of a composite film made out of formamidinium lead iodide (FAPI) and molybdenum disulphide quantum dots (MoS₂ QDs) and propose a corresponding photovoltaic device architecture based on a 'type-I' alignment of the two materials' electronic energy levels. The introduction of the MoS₂ QDs has not compromised the overall crystallinity of the FAPI film and the composite absorber has shown improved stability. We report on the benefits of this composite film and energy band arrangement as the photogenerated carriers in MoS₂ QDs, both positive and negative, are injected into the FAPI host matrix, resulting in an increased current density of 24.19 mA cm^-2 compared to a current density of 19.83 mA cm^-2 for the control de
