Recently, the team of Han Liyuan of the School of Materials Science and Engineering of Shanghai Jiaotong University has used a more economical and safe method to prepare a large-area perovskite film thinner than the flaps, which is an important step towards achieving large-scale low-cost solar power generation. The research results have been published online in Nature.
“Perovskite materials were first applied to photovoltaic technology in 2009. In just a few years, the photoelectric conversion efficiency of laboratory perovskite solar cells has repeatedly made breakthroughs, and its photoelectric energy conversion efficiency has rapidly increased to 22.1%, exceeding polysilicon. The efficiency level of solar cells, while the cost of power generation is lower than that of silicon cells. Therefore, perovskite solar cells are evaluated as the most competitive and promising photovoltaic technology in the field of photovoltaic research, "Han Liyuan said.
If the battery is to meet the practical needs, the critical area of ​​the perovskite film should be large enough and the quality should be good enough to ensure that the photoelectric energy conversion efficiency of the battery is high enough.
"We spent three years to solve this problem. Based on the preparation of large-area high-quality perovskite film, we have developed a perovskite battery module with an effective area of ​​36.1 square centimeters. It has obtained 12.1% certification for the first time in an international certification body. Efficiency has created the world record for the efficiency of the first large-area perovskite module.†Han Liyuan said that this means that the future of perovskite photovoltaic technology may be large-scale industrialization.
Experts said that this new method for preparing large-area uniform perovskite films provides a new development direction for large-scale production of low-cost perovskite solar cell modules.
Our company also has anti-fog mirrors, which are very suitable for use in the bathroom. In the bathroom, which is full of moisture and fog, when we look in the mirror, it is easy to blur, resulting in a lack of clarity. Our anti-fog mirrors prevent this from happening, so you can see any detail, even in a steamy bathroom. Not only that, but our anti-fog mirrors are also available in many styles and types of anti-fog. For example, there is automatic heating, the formation of anti-fog effect; there is also a way to heat the water by themselves, the formation of anti-fog effect.
We've also added a few more designs to our anti-fog mirror products. For example, design a shaving hook, which becomes a fog-proof shaving mirror. Can be used to hold toothbrushes and razors. This style of anti-fog mirror is not only convenient for women to take care of and make up in the bathroom, but also convenient for men's daily use. It's beautiful and practical. The products we design and produce are always developed for the needs of our customers. We are a leader in local mirror producers and have focused on this industry for 17 years.
