According to a report by the Massachusetts Institute of Technology (MIT) "Technical Review" magazine, scientists at the University of California, Los Angeles (UCLA) have developed a cheap plastic solar cell with a photoelectric conversion efficiency of 10.6%, breaking the team last year. The month created 8.6% of the photoelectric conversion efficiency.
Yang Yang and he developed plastic solar cells.
Plastic solar cells have many advantages: they are soft, lightweight, and inexpensive, but their performance cannot match that of conventional solar cells made of inorganic materials such as silicon. The research team led by Yang Yang, a materials professor at the University of California, Los Angeles, hopes to create a plastic solar cell that rivals thin-film solar cells. Finally, they used a new type of PV plastic developed by Japan's Sumitomo Chemical Industry Co., Ltd. to produce a plastic solar cell with a conversion efficiency of 10.6%. Recent research shows that later scientists can use these "picky" polymer materials to create more efficient batteries.
The new plastic solar cell contains two layers that can handle different wavelengths of light: one layer of plastic can handle visible light and one layer of plastic can handle infrared light. Yang Yang said: "The spectrum of solar energy is very wide. From near-infrared to far-infrared to ultraviolet, a single solar module can't handle it at all."
At present, the best inorganic solar cell is also a multi-layer device, but it has been facing many challenges to produce a multilayer organic solar cell. Allen Jay Haeger, who won the 2000 Nobel Prize laureate for his discovery of conductive polymers, said that the polymer can be printed from a solution, just as ink marks on paper, which is the same A major advantage of technology is also a flaw. He said: “Manufacturing multi-layer organic solar cells does not require high temperatures and the manufacturing process is simple, but finding the right solvent to print on each layer of the battery without penetrating into the underlying layer requires skill. The more layers there are, the The more complicated it becomes. In addition, it is also a challenge to match the electrical properties of each layer."
Yang Yang hopes to create a plastic solar cell with a photoelectric conversion efficiency of 15%. He said that when solar cells are out of the laboratory for commercial production, their efficiency will be reduced by about one-third. Therefore, the conversion efficiency of polymer solar cells with a conversion efficiency of 15% in laboratory tests may be only in practical applications. It is 10%. Yang Yang believes that plastic solar cells with a photoelectric conversion efficiency of 10% should be able to compete with thin-film solar cells.
How to make a request for a custom Container House? What details need attention?
Container houses can be customized and processed according to our needs. Size specifications, internal area divisions, and appearance styles can also be customized and processed. There are many different types of container houses that can be customized according to consumer needs. Custom processing. But how to put forward the corresponding requirements when customizing? What details should be paid attention to when customizing?
The overall design should be reasonable
In order to ensure the practicality of the container house, it is necessary to do a good job in the overall design when customizing the Prefabricated House. The customizable series of products need to take into account the specific floor area, internal volume, how much internal space is required, how to divide the area, etc. Generally, it is necessary to conduct on-site inspections, and to reserve the location of the corridor, etc. If the container house is used in the moving area of the construction site, then it is also necessary to ensure that the corresponding transportation channel is reserved to facilitate the staff to walk back and forth, and also to carry goods, etc., the design It is still necessary to ensure that it conforms to the situation on the spot.
Pay attention to material selection
The customizable series of products include a variety of product types. In addition to container houses, there are also custom container houses, custom light steel villas, etc. It is recommended to pay attention to the overall material of the custom. Different, the service life will definitely be affected as well. Therefore, we still have to pay attention to the specific conditions of its material. Generally, it is recommended to look at the actual product, pay attention to whether the cross section is uniform, and whether the thickness of the steel plate and the thickness of the coating are guaranteed. Moreover, we cannot ignore the details of the supporting frame, connectors and other details. We must ensure that the quality of each component is excellent, so that the container house can be used for a long time and its reliability is guaranteed.
Adjustments to blueprints
Customizable series of products may require multi-layer design, so it is recommended to make a request when customizing, and then the manufacturer will provide us with the corresponding design. If there are certain details that need to be adjusted on the design drawing, it must be completed quickly. Adjust, and then go for post-customization. Manufacturers will have their own design team, and after confirming that there are no problems in the design, they can proceed to construction.
