novel physical vapor deposition approach to hybrid perovskites: growth of mapbi 3 thin films by rf-magnetron sputtering
The method-based representation is used for the deposition of mixed organic-
High cost but efficient solar cells.
However, the solution
The process technology provides limited control over the morphology and crystals of the film, and most importantly, continuous film deposition is not allowed to produce perovskite-

Movies are single.
Phase, almost no content of the unresponsive PbI2 was detected, with full surface coverage and thickness ranging from less than 200nm to greater than 3 μm.

The phase deposition method is interested in promoting perovskite photovoltaic devices, and it is possible to manufacture perovskite multi-junction solar cells or multi-colored strong light-

Cost solar cells. Solution-
The method-based method is the most extensive method for the preparation of perovskite films, while being reliable and low-costeffective.
However, even an optimized solution
The process method is affected by the shortcomings.
One is the lack of control over low positions.
The temperature crystalline process is affected by various factors such as solvent and precursor, substrate surface properties, solvent evaporation and annealing conditions in the deposition process, which usually leads to poor repeatability of the film morphology, thickness, degree of crystal and crystal size have a crucial impact on photovoltaic performance.
The second major drawback is that the continuous deposition of the film from the solution cannot produce perovskite-
Since solvents used to deposit subsequent layers wash away the underlying layer, perovskite heterogeneous structure.
Therefore, all perovskite-based multi-junction tandem solar cells and knots are progressing very slowly.
A very promising alternative to the solution
Based on deposition technology, which has started in the past few years, has attracted a lot of interest as a possible way to overcome the above problems.
In general, due to the fine control of the vacuum environment and deposition parameters, these methods are expected to provide the purity of the pioneer and the deposited film, resulting in a high level of perovskite crystals and repeatable films.
In addition, the steam method is suitable for scale-
Preparation and large area deposition.
The steam method does not require the use of solvent and annealing steps, which is critical as it allows perovskite-on-
Perovskite deposits that create heterogeneous structures and knots.
So far, steam
The method based on vacuum evaporation process and steam-evaporation process is mainly used for the synthesis of hybrid perovsk acid salt

The relatively low deposition efficiency of the sputtering is overcome by the magnetic control-based device.
So far, no reports have been reported on the deposition of hybrid perovsk films by sputtering.

Sputtering technology allows fine tuning of deposition conditions by adjusting different parameters, such as RF-
Power, gas pressure, and target substrate distance, thus providing an excellent platform to further optimize the perovskite film, and extend the MAPI approach proposed here to any other material of interest in the Perovskite solar cell fieldPSCs).
