While there are still some doubts about the viability of perovskites in photovoltaic applications, a team from the Ecole Polytechnique Fédérale de Lausanne (EPFL) successfully deployed vacuum flash processing (VASP) technology, achieving an efficiency
of 19.
6%.
The team has achieved several breakthroughs in perovskite photovoltaic technology, including series applications
.
EPFL researchers report that this could make perovskite cells more homogeneous and have fewer impurities
.
Another advantage of using the VASP method over the Tuxuan method is that there is no need to use toxic chlorobenzene to stimulate the growth
of perovskite crystals.
Michael Grätzel, a well-known photovoltaic researcher who led the EPFL team, said: "The effective solution we have found is to apply light vacuum technology
.
By using this method, high-quality electronic-grade perovskites can be obtained at low temperatures – never exceeding 100°C
.
”
The resulting perovskite film is both smooth and completely covers the substrate material
.
What's more, the stability of perovskite cells has been improved
by the VASP method.
EPFL researchers report that the battery performance remains stable
even after 39 days of exposure to air.
