15.2%, 16.0%, 17.4%!
This is not a simple set of percentage data, but the result of three world-record breaking in a year by Hangzhou Nanna Optoelectronics Technology Co., Ltd.
In February 2017, Hangzhou Nanna Optoelectronics produced a large-area perovskite solar cell module with an area of more than 16cm2 and a photoelectric conversion efficiency of 15.24%, setting a world record for large-area perovskite photovoltaic modules.
In May 2017, the conversion efficiency of Hangzhou Nanna Photovoltaic Perovskite photovoltaic module reached 16.0%, again setting a world record in perovskite photovoltaic modules. At the 17th China Photovoltaic Symposium held on August 30, the results Selected the first edition of 'solar cell China's highest efficiency table'.
In December 2017, the conversion efficiency of perovskite PV module manufactured by Hangzhou Nanowaxo Optoelectronics reached 17.4%, breaking the world record of the perovskite photoelectric conversion efficiency maintained by itself for the third time and was incorporated into the joint editing of scientists in the United States, Japan, and Australia The "solar cell efficiency table."
Founded in July 2015, Hangzhou Nanowei Optoelectronics Co., Ltd. was founded by a team of three national hi-returnees composed of three post-85 Zhejiang University returnees.Young young people chose an equally young but promising field and are committed to creating a commercial new calcium Titanium thin film solar cell technology innovation company.
It is understood that the perovskite solar cells was first reported in 2009, when the photoelectric conversion efficiency of only 3.8%, to today's 17.4%, perovskite cell conversion efficiency has been rapid development.Compared to the traditional crystalline silicon cells, The perovskite material not only has excellent photoelectric properties, but also has abundant raw materials and low cost, and the manufacturing cost is expected to reach one-third to one-fifth of the current crystalline silicon solar cells, thus showing great commercial value. Titanium Mine 'solar cell was selected as one of the top ten emerging technologies in 2016. The world's top scientific research institutions and large multinational corporations such as Oxford University in the United Kingdom, the Federal Institute of Technology Lausanne in Switzerland, Japan's Matsushita, Sharp and other recent years have invested a lot of manpower and resources, related Of the papers reached more than 1,500 each year, and strive to commercialize this technology as soon as possible.
Stability, toxicity and other serious defects have been limited to perovskite battery in the laboratory, and Hangzhou Fiber Optoelectronics recently just moved into more than 2000 square meters of new plant, with its own production workshop, which means that the fiber-optic nanofibers from Hangzhou will A purely research and development company to R & D and manufacturing company, perovskite solar cells is expected to open the curtain of the market, and gradually out of the laboratory.
Hangzhou Nana photoelectric has a strong technical team, the company's core team members are graduated from the world's top universities in the field, all from the photovoltaic field the best mentor.It is understood that the existing capacity of the Optoelectronics 25 groups, 60 % Or above have master's degree or above, including 6 returnees.
Up to now, Finet Optoelectronics has declared and obtained over 40 intellectual property patents in the research and development of perovskite solar cells, advanced semiconductor production equipment and thin-film photovoltaic testing equipment, etc. In 2017, the company has invested more than 40 million yuan in research and development.
