Abstract
There are various aspects to be considered in
defining degradation of perovskite solar cell.
This paper will discuss the factors which causes
solar cell degradation. Computational design is
the analytical technique of viewing the cell and
using the analysis to see the outcomes like how
to make it more efficient or how to remove the
degradation in this technology. Bio magnetic
perovskite solar photovoltaic cells have shown
an efficiency of power conversion comparable
with known photovoltaic innovations, but low
operating stability inhibits their marketing and
pervasive use. There are many possible
degradation pathways, most of them being
poorly defined on the nanoscale, because of the
complexity in characterizing the complex
nanostructure of a perovskite solar cell. The
study examines the application of on-site and
operating electron microscopy to visualize
dynamic processes occurring in perovskite solar
cells as a microscope column contains various
stimuli.
1.0 Introduction
The first step to enhancing the stabilization of
the perovskite cells is to understand the actual
cause. Much can lead to degradation of
perovskite crystal, and such aspects can be split
in two different categories, alien and intrinsic.
The following are both discussed. Since the next
generation of PSCs attract a lot of attention.
Despite their relatively short development
period, this is because of their efficiency with
which they convert power, in relation to its low
cost. A range of halide perovskites with ABX3
stoichiometry that are used as photo absorbers
are essential components of PSCs. Due to their
remarkable optoelectronic characteristics,
photovoltaic technology has made progress.
However, these materials must be further
enhanced to improve their functionality and be
highly efficient and stable for commercialization
for the coming generations. Solar cells, devised
in the 1960's, are without a doubt most efficient
instruments for the collection of solar energy.
Solar cells directly use the photovoltaic (PV)
effect to turn solar light. Several solar cell types
have been developed so far and placed on the
market; the market share for single-crystalline
pc-Si was 69.5% by 2015, for polycrystalline
pc-Si 23.9% and for thin-film pc-CdTe solar pc-
Si 6.6% by 2015[3]. Indeed, power
transformation (PME), manufacturing cost and
device stability are the most important factors
deciding the competence of solar cells on the
market (Doityourself.com, 2019).
The research questions will help in formulating
the area to be researched. These questions have
been highlighted below.
RQ1: What are the causes that result in
degradation of Perovskite Solar Cell?
RQ2: what exactly is perovskite solar cell
RQ3: what are computation methods that can be
used to analyze Perovskite Solar Cell

2.0 Literature review
The fast rise in effectiveness of many Solar Cell
scientists has become a warm place for the
studies of hybrid organic inorganic metal halides
perovskite solar batteries (PSCs) over the last
few years. The use of perovskite components in
solar panels has progressed quickly due to the
outstanding heat consumption, load carrier
mobility, and service life of the material, which
have resulted in the efficiency of the unit,
offering important possibilities for low cost
industrial scalability. This low price and
scalability potential involve overcoming
obstacles to stabilization and compatibility with
the environment. However, a perovskite-based
technique offers transformative opportunities for
fast terawatt solar implementation, if these
issues are resolved. The perovskite fabrics
demonstrate different benefits, such as lengthy
propagation distances, a widely tunable belt gap
with a large capacity for light consumption. The
cheap manufacturing methods and elevated
effectiveness make PSCs similar to Si-based
solar cells. However, disadvantages such as
system instability, JV hysteresis, and toxicity
decrease further development and potential
marketing of PSCs.
This evaluation starts on the basis of latest study
results with regard to the crystal and electronic
structure of perovskite. More information on
every part, system buildings, significant
production techniques of devices and the
efficiency of the PSCs obtained using each
technique is used to analyze the development of
PSCs. The following section of this analysis
discusses significant obstacles to the marketing
of PSCs. The impact on the stability of PSCs of
the crystal structure, manufacturing temperature,
humidity, oxygen and UV are discussed. There
is also discussion of the stabilization of other
elements in the PSCs (Hallam et al., 2017).
The meaning of the first term "perovskite"
related to the microstructure of calcium titanate
uncovered by the German mineralogist Gustav
Rose in 1839 on which it was named after Lev
Perovski of Russian mineralogy. Ever since, all
elements of the same crystal composition as
calcium titanate have been referred to as
perovskites. The general formula of ABX3 is the
perovskite light absorption layer where A is
organically cated (eg, CH3NH3 +
methylammonium), B is metallic (e.g., Pb2 +),
and X is halide anion.

2.1 perovskite cell fabrication
The structural differences between PSCs both
with DSSC and thin-film PVs could also lead to
significant enhancement of PSCs in the
manufacturing approaches for both solar cell
types, including virtually all void and non-
substantial techniques. However, the current
study showed something else: spin-coating is the
most frequently used technique for producing
PSCs thanks to the comparatively simpler
process and high effectiveness.
There have also been many other non-vacuum
methods established and referred to below.
Some of these were also effectively
implemented for manufacturing, including
physician blading and screen printing.
Due to its simpler procedure and low price, one-
stage deposition was commonly used in
perovskite cell production. The perovskite film
can be manufactured using pinhole-free sthetics
with a wise command of perovskite precursors.
The prototype sample of perovskite was usually
produced using gamma-butyrolactone,
dimethylformamide (DMF), dimethyl sulfoxide
(DMSO) or a mixture of two or all three
solvents, boiled in organic halides (MAI / FAI,
methylammonium / formamidine yodide) or
synthetic halides (e.g., Pbi2). The merged
precursors were spin-coated, scrub-free and
thick semiconducting layers in the range 100-
150 BC (Xu et al., 2018).
2.2 Causes of degradation
Perovskite solar panels have an incredible
efficiency and give "a new type of solar cell"
that is inexpensive to produce and can be semi-
transparent, lightweight and versatile. ⠀ The
comparison of perovskite with silicon solar
panels is provided in Figure 1.
