Abstract
Interfacial
defects
and
environmental
instability
at
perovskite
surfaces
pose
significant
challenges
for
inverted
solar
cells
(PSCs).
Surface
post-treatment
strategies
have
emerged
as
a
viable
approach
to
improve
film
quality
passivate
defects.
Although
organic
molecules
can
both
grain
boundaries
via
hydrogen
or
covalent
bonding,
their
limited
adsorption
specificity
often
results
in
incomplete
defect
neutralization.
In
this
work,
we
introduce
bilayer
passivation
employing
phenethylammonium
iodide
(PEAI)
n-octylammonium
(OAI)
concurrently
mitigate
non-radiative
recombination
stability.
PEAI
passivates
undercoordinated
Pb
2+
surfaces,
effectively
eliminating
deep-level
traps
suppressing
losses.
Meanwhile,
OAI
forms
hydrophobic
barrier
on
the
surface
through
its
long
alkyl
chains,
inhibiting
moisture
penetration
without
compromising
interfacial
charge
transport.
As
result,
exhibits
significantly
enhanced
optoelectronic
performance
stability,
achieving
champion
power

efficiency
(PCE)
of
24.48%.

candidates
for
realizing

Despite
