Vehicle-integrated photovoltaics (VIPV) is gaining increasing attention as automakers look for ways to extend electric vehicle (EV) range and improve energy self-sufficiency. A recent development by China-based Hefei Puskai New Energy Technology highlights the potential of perovskite solar technology to enable such solutions.
According to a report by Perovskite-Info, Hefei Puskai has developed what is described as the first 300 mm × 300 mm integrated perovskite curved automotive photovoltaic glass (CIPV) in collaboration with a domestic automobile manufacturer (Perovskite-Info, 2026). The technology combines perovskite photovoltaic layers with curved automotive glass through an integrated molding process, enabling solar power generation directly from vehicle surfaces such as roofs, sunroofs, and hoods.
The module reportedly utilizes the company’s patented perovskite CVD dry-process deposition technology, allowing the photovoltaic layer to be formed while maintaining the curvature required for automotive glass components. Compared with conventional rigid crystalline-silicon modules, curved perovskite photovoltaic glass offers several advantages, including higher light transmittance, improved weather resistance, and better compatibility with complex vehicle geometries.
Importantly, the integrated design addresses key challenges that have limited earlier attempts at automotive photovoltaic integration. Traditional flexible solar films bonded to glass often face issues such as uneven adhesion, bubbling, wrinkling, and increased thickness that affects vehicle aesthetics. By integrating the photovoltaic layer directly during glass molding, these manufacturing and durability issues can potentially be mitigated.
Industry experts believe that perovskite photovoltaic coatings could significantly expand the solar-active area on vehicles. According to Ouyang Minggao of the Chinese Academy of Sciences, transparent perovskite films could cover up to 10 m² of a vehicle’s surface, potentially generating 6–8 kWh of electricity per day, sufficient to support typical commuting needs (Perovskite-Info, 2026).
While still at the pilot stage, the development represents an important step toward scalable solar-assisted electric mobility. Hefei Puskai plans to continue sample testing, pilot-line construction, and automotive certification to accelerate commercialization.
