The new type of thin-film solar cell has taken another step towards mass production.On the 26th, the international academic journal Science published the research results of Academician Huang Wei's team at Northwestern Polytechnical UniversityStabilizing black-phase formamidinium perovskite formation at room temperature and high humidity（《 The study proposes the preparation of stable methylamino calcium perovskite at room temperature and high humidity,In a multifunctional wayIonic liquids are used as solvents to replace traditional toxic organic solvents in the preparation of perovskite photovoltaic materials.
Prepared by ionic liquidFAPbI3 material has a neat and regular internal structure (right), greatly improving the stability and photoelectric conversion efficiency of the material.
This method not only has high stability and simple preparation process, but also improves the photoelectric conversion rate, solves the stability problem in the traditional preparation process, and achieves a major breakthrough in the field of photovoltaics, creating a prerequisite for the large-scale production and utilization of perovskite solar cells.
Academician Huang Wei's team has developed a new type through original innovationIonic liquids, as solvents, solve the bottleneck problems of unstable materials, complex process preparation, and high pollution. Ionic liquids are like 'shepherds' on the grassland, playing a commanding and arranging role in the molecular composition of perovskite, which is the' flock '. After stabilizing its formation, it silently exits. This new formation is the stability of the perovskite battery we want to obtain, "explained Chao Lingfeng, the author of the results and a doctoral student at Northwestern Polytechnical University.
Foldable flexible electronic products developed by the team
The following is a video of CCTV reporting a major breakthrough in the preparation of solar cells
The equipment used by the researchers in the video (highlighted in red) is from Jiangsu Leibo Scientific Instrument Co., Ltd. (hereinafter referred to as "Leibo")The IC5000-S temperature controlled glue homogenizer developed by "Leibo Instrument". In response to the pain points of difficulty in preparing solar cells in atmospheric environments and achieving industrialization, the advantages of temperature controlled spin coating technology are clearly reflected, which indirectly reflects that temperature controlled spin coating is an important process in the field of solar cell preparation. At the same time, it also reflects the adaptability and professionalism of Leibo's IC5000-S temperature controlled homogenizer in the field of perovskite.
