According to reports, China-based Hefei Puskey New Energy Technology, in cooperation with a leading domestic automaker, successfully developed the first 300mm×300mm integrated perovskite curved automotive photovoltaic glass (CIPV). This marks a key advance in perovskite automotive photovoltaic technology in terms of integrated curved molding, large-area preparation and vehicle adaptability, providing a new solution for energy self-sufficiency in new energy vehicles.
The curved automotive perovskite photovoltaic glass utilizes the company's independently developed patented perovskite CVD dry process technology and integrated molding process for curved automotive glass. While maintaining a standard 300mm×300mm pilot-scale size, it achieves stable matching with the curvature of the vehicle body. Compared to other automotive photovoltaic systems, the curved perovskite photovoltaic glass, molded integrally with glass, boasts high light transmittance, high weather resistance, and high power generation efficiency. It can be directly integrated into curved areas such as roofs, sunroofs, and hoods, significantly improving adaptability. This adresses industrialization pain points such as uneven bonding of flexible perovskite films to glass, bubbling and wrinkling, poor adhesion, and excessive thickness affecting aesthetics. It can provide vehicles with a range extension of over 20 kilometers, driving a CIPV market scale of over 10GW.
Ouyang Minggao, an academic at the Chinese Academy of Sciences and vice chairman of the China EV100, stated that compared to rigid crystalline silicon batteries, transparent perovskite films can be laid across the entire vehicle body to absorb energy, covering an area of up to 10 square meters, which is five times the coverage area of crystalline silicon photovoltaics. Using this technology, 6 to 8 kilowatt-hours of electricity can be provided daily, sufficient to meet the basic needs of a typical commute.
This achievement could accelerate the use of perovskite technology in automotive photovoltaic applications, helping new energy vehicles achieve an upgrade in range. Looking ahead, the company will advance sample testing optimization and pilot line construction, accelerate automotive certification and market application, and provide core photovoltaic new material support for the country's new energy and intelligent connected vehicle industry.
