DEVELOPMENT OF
PEROVSKITE SOLAR
PANELS
Since 2016, the Group has been engaged in the 'Perovskite Solar Module
Development' project in cooperation with the Faculty of Materials
Science of Moscow State University (MSU). The project implementation
was supported by the Federal Target Programme until 2019, and is
currently supported by the Russian Scientific Foundation. In 2021, the
research yielded the following results:
HYDROGEN
ENERGY
DEVELOPMENT
En+ Group embarked on a new development in
hydrogen energy in 2021. With its massive green
energy opportunities, En+ is considering hydrogen
production by electrolysis using hydrpower. In addition,
the Company is interested in facilities for hydrogen
transportation over long distances and is considering a
project to develop, jointly with partners, cryogenic tank
containers for liquid hydrogen transportation.
STRATEGIC REPORT
En+ Group Annual Report 2021
A new method of multilayer
sealing (encapsulation) of
perovskite solar cells that does
not damage the light-absorbing
and organic conductive layers
of the devices was developed.
The efficiency of encapsulated
perovskite solar cells is over 19%
and it does not decrease after
the devices have been stored
in humid air for >1,500 hours,
which proves a high resistance
to atmospheric factors at
ambient temperatures. The
samples demonstrate high
photostability: encapsulated
solar cells retain 93% of the
initial efficiency after 1,000
hours of irradiation with white
light with a power of 90-110 MW
at a temperature of 21-28°C.
The optimum conditions for the
synthesis of single-phase hybrid
perovskite films with the target
morphology and composition
were confirmed by applying
reactive polyhalide ink to the
surface of a lead-containing
precursor film and immersing
the precursor film in a solution.
of iodine and polyhalides in
non-polar solvents. The high
photostability of the synthesised
films was demonstrated in
comparison with the samples
synthesised using the classical
solution technique.
Test perovskite solar cells with
an efficiency of more than 17%
were produced using improved
approaches to the synthesis of
AMX3 films using polyhalides.
It was demonstrated that the
solar cells produced using
the approaches developed by
the project team are highly
competitive with conventional
test samples in terms of
photostability and retain at
least 99-100% of the initial
efficiency after exposure to
>800 hours of white light
irradiation at 100 MW/cm² in
humid air at room temperature.
New computer modelling
and machine learning
algorithms were
developed to predict
the properties of hybrid
perovskite-like materials.
