    as hole transporter bilayer for high-performance perovskite solar cells

## Description

- description: Hole transport layers (HTLs) are one of the most significant elements
    influencing the performance of perovskite solar cells (PSCs). PEDOT:PSS (= Poly
    (3,4-ethylenedioxythiophene):poly(styrenesulfonate)) is regarded to be the most
    conducting polymer to use as an organic HTL for the inverted structure of PSCs.
    Due to the highly acidic behavior, PEDOT:PSS-based PSCs have shown limited stability.
    Additionally, the valence band mismatch of the PEDOT:PSS layer with the adjacent
    perovskite layer often results in low open-circuit voltage (VOC) of the overall
    PSC. To address these issues, we have incorporated a thin layer of ethylenediamine
    functionalized graphene (EDA-FG) between the indium tin oxide (ITO) anode and
    the PEDOT:PSS layer yielding a bilayer HTL. The new bilayer successfully matches
    the energy valence band at the HTLs/ perovskite layer interface. The photoluminescence
    (PL) confirms that the deposited EDA-FG/PEDOT:PSS quenched the perovskite layer
    more than PEDOT:PSS. Based on the enhanced electrical and optical properties,
    a champion PCE of 17.66% was obtained for the respective PSCs. Additionally, the
    PSCs showed stable photovoltaic behavior up to 500 h.
