And yet, some researchers in the region focus on breaking the power-transformation efficiency records, reaching some types of perovite cells. 27 percentThese achievements can lead to papers in higher IMPACTea magazineLS, BUnion territories Do twoTo take out perovesites out of the door.
Many researchers say Its Time to prevent the target for incremental efficiency benefits and focus on scale to manufacture and improve the lifetime of cells. This will include developing manufacturing technology that balances between high quality devices and low production costs,
it Will not done be easy. Reducing processing costs while increasing cell lifetime and maintaining high efficiency will require much more research and effort. But if academic and industrial researchers are united, this manufacturing challenge can be resolved more than one quickly,
Perovsite solar cells are made up of organic ions, metals and halogen that create a special crystal structure that makes them very versatile. With the correct composition, perovesite can be better than silicon in converting sunlight into electricity: they have a 34 percent theoretical efficiency range compared to 32 percent of silicon. They can get it with a very thin layer of materials, allowing them to be used in innovative ways such as flexible solar cells, curved solar panels, indoor photovolta and solar windows.
Perovskite developer Tandem PV states that perochet layers produced with solutions-based processes should not be made perfectly in passive conditions. Tendem P.V.
Perovsites can also be stacked on top of silicon photovoltaic to improve performance. Perovskite-Silicon Tandem stands on the current record efficiency of solar cells 34.6 percentAn impressive 7 percent improvement compared to the best silicone cells.
But the construction of high quality perovsite at low cost has proved challenging. Early performance can be obstructed to exposure to air and moisture during processing and cause a decline over time. This has forced researchers to collect them in highly controlled environment.
Within these controlled environments, there are two ways to create perochetite solar cells. More expensive route-vapor deposition-evaporating or evaporating the perovesite content under the Volves vacuum conditions and then depositing them as a thin film. It makes very high quality films with some defects and reliable efficiency. But the set-up cost is high for this method, and harsh maintenance and high environmental control Necessary,
The simple and inexpensive method involves accumulating perochette layers using inkjet printing or spray coating. In these solutions-based approaches, the perovesite content is dissolved in a precursor solution or “ink” and applied directly to the desired surface or substrate. The simplicity of this technique has enabled researchers to rapidly improve perovesites in the last decade. However, these techniques allow a lot of space for contamination and defects.
Either with the passage, to produce the highest performing cells, construction usually occurs in a controlled environment such as a laboratory glove box. This device pumps oxygen and moisture, replacing it with non-reactive gas such as nitrogen. However, an increase in the amount of environmental control can increase costs.
Some gloves boxes can bring internal oxygen and moisture levels to less than 1 part per million (ppm). But install and maintain These systems are expensive. This level of environmental control requires a complex loop of filters and blower systems to contain contaminated air, it is purified, then it is rearranged into the system. These filters and control systems require regular maintenance and replacement, which Raise maintenance costs. The PPM sensor alone can cost thousands of dollars.
These maintenance costs will always be on scale with volume. The larger the environment, the more air needs to be filtered, and it is difficult maintain Strict environmental control. it Necessary More powerful fans, large filters, and if these systems are in contact AtmosphereThey will cost more time and money to work again.
Ways of innovative perocyte manufacture
These challenges have inspired solar developers to experiment with various construction methods for perovesite devices, especially on a large scale. For example, Power roll Durham, in England, who is developing flexible solar modules, Currently taking one The solution-based approach simultaneously evaluating other methods. “We cooperate with both industrial and academic partners to be constantly at the forefront of construction techniques. This ensures that we keep options open for both vacuum and solution procedures,” says. Nathan HillA senior scientist in power roll.

One in 2018 interviewOxford Kofounder Henry Snath indicated that his company could take the vapor route when he said “vapor-dipo-dipposed cell (will) would move faster than the solution-related cells.”
The spin coating technique accumulates perovicite layers using the centripetal force to spread the material equally in a substrate. Doing this process inside a glove box, where oxygen and moisture are controlled, helps improve performance. Ossila
Completely passive processing – Very little PPM-Not there. Ideal for mass production, many manufacturers say. so They are searching for an innovative approach to simplify the construction. “While we admit that processing in active conditions can be beneficial for lab-scale production, we and our partner find that controlling temperature and humidity is the major factor for the management of perovsite grains. Development,And There were promising consequences working outside the inert environment,, Says on the hill Power Roll. Another Perovsite Innovator, Tendem P.V. San Jose, in California,, according to a spokesman of the company, processes its perocyte layers from the solutions outside the inertial conditions.
As the manufacturers continue to use, researchers should also revaluate their goals for perovicite solar cells. Usually, the more inactivity is the environment, the greater Solar cell performanceBut how high these cells perform – and how do these environment do – really have to Happen? Is there a middle ground where the environment is partially controlled, and as a result perovsites are still of high-lid quality?
My colleagues and me ButOssila Pass Exhibited Triple-Castion Mixed-Perovsites, which are Relatively strongCan be firmly made in one glove box He Is said Only 15 ppm humidity and 0.5 percent oxygen level (5000 ppm). These solar cells gained capacity compared to the people made in high-end glove boxes (19.2 percent compared to 19.7 percent respectively). The equipment that reach 19 percent is under competition with silicon solar technology (which) Overdose 13-23 percent efficiency, depending on the type of solar cell). Because perovesites are best used in conditions where silicon cannot be used, or in combination with silicone devices, we think it is an impressive result.
We also found that when the same perovesites (triple cations mixed halides) are processed in the ambient air with a solution-based approach, the equipment still performed well. The best result, which reached 17.6 percent, prompt Good air-practiced perocyte is expected to solar cells.
Tariffs on silicon solar can make perovesite more competitive
Many academic researchers are also experimenting with creating perochet solar cells outside the glove box environment. A recent studyIn Nature Communications A solution-developed roll-to-rol perochetite is described completely in the ambient air. (Roll-to-rol processing involves high speed construction that can continuously collect solutions on flexible materials on moving rolls. Its Like newspaper printing, but for solar cells.)
Researchers at Australia’s National Science Agency, Sisro, last year, performed a completely roll-to-rol-fabricated perovesite solar cell under the position of the ambient room last year. CSIRO
The resulting equipment reaches a capacity of 15.5 percent for individual cells and 11 percent for mini-summer modules. What is More, the estimated production cost is as low as $ 0.70 per watt and still has a forward space for cost cuts.
To transfer the area to complete commercialization, Its It is important to place scalable processing methods rather than focusing more than focusing more. Academia and industry should align their goals of increasing stability and scalability.
Perovsite is within commercialization access to solar cells. And eInternational trade status may give perochette Solar cellSA competitive edge.
