On July 31, the 2025 Photovoltaic Industry Quality & Innovation Forum and Advanced Photovoltaic Demonstration Technology Seminar successfully concluded in Lanzhou, Gansu Province.
The seminar was jointly organized by the China Huaneng Group Clean Energy Research Institute, the National Center of Supervision and Inspection on Solar Photovoltaic Products Quality (CPVT), Huaneng Gansu Energy Development Co., Ltd., and Huaneng (Jiayuguan) New Energy Co., Ltd. The event aimed to promote technological innovation and quality improvement across the photovoltaic industry.
As a leading manufacturer of photovoltaic encapsulation materials, Betterial was invited to participate and delivered a keynote presentation showcasing its latest research achievements in encapsulation technologies for perovskite and perovskite tandem solar modules.
Showcasing Advanced Encapsulation Technologies for Perovskite Solar Modules
During the seminar, Geng Feng, Head of Betterial’s Product Testing & Inspection Center, delivered a presentation titled:
“Selection of Encapsulation Films for Perovskite and Perovskite Tandem Modules Across Diverse Application Scenarios.”
The presentation introduced Betterial’s latest research and technological advancements in encapsulation solutions for perovskite and tandem perovskite solar modules, with particular emphasis on the advantages of its solutions under different application environments.
Mr. Geng noted that long-term stability remains one of the primary challenges limiting the commercialization of perovskite photovoltaic technology, and that encapsulation technology plays a critical role in ensuring module durability and reliability.
Betterial has long been committed to the reliability research of encapsulation materials for perovskite and tandem perovskite modules. Its latest Betterial® Perovskite & Perovskite Tandem Encapsulation Film adopts an advanced thermoplastic encapsulation technology, overcoming the temperature limitations of conventional encapsulation processes.
Key advantages include:
- Excellent crosslinking performance under low-temperature lamination
- High peel strength after lamination
- Low-temperature processing suitable for sensitive perovskite devices
- Improved long-term module stability and reliability
In addition, the product features a unique peroxide-free formulation, effectively eliminating the risk of chemical corrosion caused by peroxide decomposition residues commonly found in traditional crosslinking encapsulation films. This significantly enhances the long-term stability and operational reliability of both perovskite and tandem perovskite photovoltaic modules.
Advancing Quality Across the Photovoltaic Industry
During the concurrently held 2025 Photovoltaic Product Quality Data Analysis Conference, leaders from industry associations, experts from CPVT, representatives from major power generation companies, and enterprises across the photovoltaic supply chain engaged in in-depth discussions on improving photovoltaic product quality.
The participating experts emphasized that, as global photovoltaic installations continue to expand rapidly, the industry must further strengthen technological innovation and quality management. Representatives from industry associations, CPVT, and leading power companies all called for higher quality standards throughout the photovoltaic value chain.
At the conference, companies from across the industry shared their latest innovations and quality improvement initiatives, expressing their commitment to driving the photovoltaic industry toward a future of higher quality, greater efficiency, and enhanced sustainability through continuous technological innovation.
Looking ahead, Betterial will continue to deepen its expertise in photovoltaic encapsulation materials while strengthening collaboration and technical exchanges with partners across the industry.
By continuously exploring next-generation photovoltaic technologies and delivering innovative encapsulation solutions, Betterial remains committed to supporting the global energy transition and contributing to the achievement of carbon neutrality through advanced materials and technological innovation.
