Abstract
The long term stability of air processed inkjet
infiltrated carbon based perovskite solar cells (CPSCs)
is investigated under intense ultra-violet light soaking
equivalent to 1.5 Sun UV light illumination. Two batches
of the fabricated CPSCs were exposed systematically i.e.
first without implementing any protective coating and
then epoxying the CPSCs through a low cost commonly
available epoxy which was applied to serve as a barrier
against moisture and humidity intrusion. The CPSCs with
no protective layer against moisture and humidity
exhibited impressive preliminary stability for hundreds
of hours during their exposure to intense UV light and
provided great motivation to test the CPSCs further with
more optimization. As a result, the CPSCs having commonly
available epoxy as a protective barrier exhibited
remarkable durability and showed no performance
degradation for a period of 1002 hours under intense and
continuous 1.5 Sun equivalent UV light illumination
proving that the technology is clearly not inherently
unstable and that future developments might lead to
market breakthroughs.
