Shenhua Photovoltaic and Thermal Energy Technology Accelerate the Industrialization of Perovskite Tandem Solar Cells 

Recently, Beijing Yaoneng Technology Co., Ltd., a company focusing on the development of perovskite tandem solar cells, signed a strategic cooperation agreement with Shenhua (Beijing) Photovoltaic Technology R&D Company (hereinafter referred to as Shenhua Photovoltaic R&D Company) under the National Energy Group. Develop technologies related to perovskite tandem batteries and promote their industrial application.

​

NICE Solar Energy is a Sino-foreign joint venture controlled by the National Energy Group Beijing Research Institute of Low-Carbon and Clean Energy and jointly funded by Shanghai Electric Group, Germany's Manz Group, and Beijing Future Science City. There is a research and development center, and a 44MW copper indium gallium selenide (CIGS) thin film battery pilot line is built in Beijing. In 2017, Shenhua Photovoltaic R&D Company wholly acquired Manz CIGS Techno-logy, a R&D subsidiary of Germany's Manz Group, and has the R&D and industrialization capabilities of supporting equipment. Recently, it has set a new world record of 17.6% total area efficiency of CIGS battery mass-produced modules.

​

  Beijing Yaoneng Technology Co., Ltd. was established in 2017. TusStar Ventures completed the seed round investment in 2018. It is one of the earliest teams in the world to carry out the industrialization research and development of perovskite solar cells. The team members of the company have started the research and development of perovskite solar cell technology in the United States since 2013, and published a large number of related results in many top journals such as "Science", focusing on the core of perovskite tandem cell technology and material stability improvement. technical field. After years of accumulation and development, the company has cultivated and reserved a large number of top talents in the industry and built a systematic intellectual property system and technical barriers. In 2019, a high-standard R&D center was built and put into use in Beijing to accelerate the industrialization process.

​

Investors of TusStar Venture Capital believe that the advantages of perovskite materials such as high conversion rate, low cost, and low production requirements are obvious, but the issue of stability and industrial application has always been a problem that investors are very worried about. The thermal energy technology team has been deeply involved in the field of perovskite for many years, and once broke the world record of conversion efficiency. In recent years, the team has been focusing on the breakthrough of stability and stacking technology. The level of efficiency determines the upper limit, and the stability determines the lower limit, which is the threshold for the industrial application of perovskite technology. TusStar Ventures also highly recognizes that Yaoneng takes the stacking technology route. Considering the difficulty of realizing industrialization technology and the existing industrial infrastructure, this is a relatively easy to achieve industrialized product requirements and fast entry. The route of industrial application. It is believed that through the strategic cooperation with Shenhua Photovoltaic R&D Company, Thermal Energy will deeply integrate the R&D resources of both parties, accelerate the industrialization process of domestic perovskite tandem solar cells, and contribute hard technology to the upgrading of the photovoltaic industry.
