The efficiencies of perovskite solar cells (PSCs) are now reaching such
consistently high levels that scalable manufacturing at low cost is becoming
critical. However, this remains challenging due to the expensive
hole-transporting materials usually employed, and difficulties associated with
the scalable deposition of other functional layers. By simplifying the device
architecture, hole-transport-layer-free PSCs with improved photovoltaic
performance are fabricated via a scalable doctor-blading process. Molecular
doping of halide perovskite films improved the conductivity of the films and
their electronic contact with the conductive substrate, resulting in a reduced
series resistance. It facilitates the extraction of photoexcited holes from
perovskite directly to the conductive substrate. The bladed
hole-transport-layer-free PSCs showed a stabilized power conversion efficiency
above 20.0%. This work represents a significant step towards the scalable,
cost-effective manufacturing of PSCs with both high performance and simple
fabrication processes.
