Making a Global Debut! Zhongshan Guangji Green Energy Unveils Perovskite BIPV Power-Generating Glass in Düsseldorf

Making a Global Debut! Zhongshan Guangji Green Energy Unveils Perovskite BIPV Power-Generating Glass in Düsseldorf

Glasstec in Düsseldorf, Germany—the world’s premier event for the glass industry—serves as a core platform for showcasing cutting-edge technologies and innovative products across the entire global glass supply chain. With a focus on low-carbon and zero-carbon building materials, the event brings together industry experts and partners from around the world. At this year’s exhibition, a BIPV (Building-Integrated Photovoltaics) transparent perovskite power-generating glass—jointly developed by Zhejiang Zhongli Glass, Beijing Haiyang Shunda Glass, and Zhongshan Guangji Green Energy New Material Technology Co., Ltd.—will make its global debut.

Guangji Green Energy has long specialized in the R&D of perovskite-heterojunction tandem technology. The company provides mature perovskite power-generation solutions to traditional glass manufacturers, enabling them to produce highly efficient, flexible, and commercially viable transparent power-generating glass. This facilitates the transformation of conventional architectural glass into energy-generating building materials.

The showcased transparent perovskite power-generating glass strikes an optimal balance between high energy-conversion efficiency—reaching up to 18.6%—and excellent optical transparency, with a light transmission rate of up to 83.2%. This overcomes the long-standing industry challenge of having to choose between power generation and transparency. Retaining the structural integrity and installation characteristics of standard architectural glass, the product can be seamlessly integrated into applications such as curtain walls, skylights, and photovoltaic doors and windows. It ensures natural daylighting and aesthetic appeal while continuously generating green electricity, offering a brand-new solution for zero-carbon buildings.

Unlike a conventional single-component manufacturing model, Guangji Green Energy (Guangji) pursues a strategy of open technical collaboration. Leveraging a mature perovskite tandem technology framework and working in deep synergy with leading domestic glass manufacturers, the company integrates perovskite photovoltaic (PV) technology with established glass-processing techniques. This approach enables the rapid deployment of standardized, highly adaptable transparent power-generating glass, helping traditional glass enterprises enter the emerging BIPV (Building-Integrated Photovoltaics) sector.

Amid the global transition toward low-carbon architecture and ongoing decarbonization efforts, transparent power-generating glass—which offers the combined benefits of natural lighting, aesthetic appeal, and electricity generation—is emerging as a core innovation in the field of building-integrated photovoltaics. At *glasstec*, a world-class industry platform, this jointly developed perovskite transparent power-generating glass made its global debut, showcasing the advancements in the industrialization of Chinese perovskite BIPV technology to international markets.

Looking ahead, Zhongshan Guangji Green Energy New Material Technology Co., Ltd. remains committed to the continuous iteration of its perovskite heterojunction tandem technology. By deepening collaborations across the glass industry supply chain, the company aims to deliver stable, high-efficiency perovskite PV solutions. In partnership with a growing number of glass enterprises, Guangji seeks to drive the global adoption of transparent power-generating glass in the construction sector, contributing to the realization of "dual carbon" (carbon peaking and carbon neutrality) goals within the built environment.
