Recently, the team led by Liu Shengzhong, a researcher of the Department of Solar Energy Research of the Clean Energy National Laboratory of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and the Shaanxi Normal University, cooperated with Shaanxi Normal University to produce a flexible perovskite solar cell with an efficiency of 16.09% using solid-state ionic liquids as electron transport materials. , Breakthrough the highest efficiency of current flexible devices. The relevant results were published in the "Advanced Materials" (DOI: 10.1002/adma.201600446).
According to the website of the Chinese Academy of Sciences, flexible solar cells have attracted wide attention due to their advantages of light weight, portability, ease of transportation, and installation. At present, high-performance perovskite solar cells adopt a typical sandwich configuration (cathode/electron transport layer/perovskite light absorption layer/hole transport layer/anode). General interface layer materials require high temperature processing (>450°C), which not only increases energy consumption, but also limits the use of highly efficient flexible perovskite solar cells. In response to this problem, the team used magnetron sputtering to prepare a highly transmissive, high-carrier mobility titanium oxide electron transport layer at room temperature. The efficiency of the flexible perovskite thin-film cell based on this material was 15.07%. The highest efficiency at the time. The relevant results are published in "Energy Environmental Science" (2015, 8, 3208-3214, DOI: 10.1039/C5EE02155C).
Recently, the team found that the use of a solid state ionic liquid as an electron transport material for a perovskite solar cell can effectively improve the efficiency of the device, and can also well suppress the current-voltage hysteresis effect in the device, and the prepared flexible cell efficiency reaches 16.09. %, breaking the highest efficiency of current flexible devices. The excellent device performance is mainly attributed to the fact that the ionic liquid has a good photorefractive effect, a high electron mobility, and a suitable energy level, while the ionic liquid can reduce the defects of the perovskite film. This research result provides a practical way to realize the promotion of low-cost, large-area flexible perovskite solar cells.
The research was funded by the Central University Fund, the Yangtze River Scholars and the Innovation Team's "111 Plan" and "Thousand People Plan" projects.
Lathe parts processing refers to the manufacturing process of creating custom metal parts on a lathe machine. Lathe machine is a versatile tool used in various industries including automotive, aerospace, and electronics. Lathe parts processing involves using a lathe machine to cut, shape, and form metal parts according to the required specifications.
The process of lathe parts processing involves several steps. First, the metal material is selected based on the specific requirements of the part to be produced. Once the material is chosen, it is loaded onto the lathe machine, and the cutting process begins. The lathe machine is programmed to move the material towards the cutting tool, which removes material to create the desired shape and dimensions.
Lathe parts processing can produce a wide range of parts in varying shapes and sizes. Lathe machines use a variety of cutting tools, including drills, taps, and reamers, to produce parts according to the required specifications. Additionally, the lathe can produce components with varying levels of complexity, from simple cylindrical shapes to more complex shapes with intricate details.
One of the significant advantages of lathe parts processing is its ability to produce large quantities of parts with high accuracy and consistency. Lathe machines can be programmed to produce the same part repeatedly, ensuring consistency and quality control. This is especially beneficial in industries where a large volume of identical parts is required.
Another advantage of lathe parts processing is its versatility. Lathe machines can be used to produce parts from a variety of materials, including metals, plastics, and composites. Additionally, lathe machines can produce parts with various finishes, such as polished or textured surfaces.
In conclusion, lathe parts processing is an essential manufacturing process in various industries. It offers the ability to produce customized parts with high accuracy and consistency, which is vital in industries where quality and precision are critical. With the ability to produce parts in large quantities, lathe parts processing offers a powerful solution for a wide range of applications.
