Recently, Zhongshan Guangji Green Energy New Materials Technology Co., Ltd., together with its distributors, successfully completed sample testing for its perovskite tandem photovoltaic glass and obtained CE certification in accordance with international standards. This milestone demonstrates the company's systematic capabilities in product R&D, encapsulation processes, and environmental durability, enabling it to consistently supply domestic and international customers with stable, safe, and reliable BIPV (Building-Integrated Photovoltaics) products.

As a core international standard for the design qualification and type approval of crystalline silicon PV modules, IEC 61215-2:2021 is an authoritative testing specification widely recognized and adopted across the global PV industry.

The tested samples measured 300mm × 300mm (0.09 m² per unit). Under Standard Test Conditions (STC): ✅ The photoelectric conversion efficiency reached 18.62%, exceeding the ≥18% technical benchmark for high-end curtain wall products; the peak power was 16.76 Wp per unit, with a power density of 186.2 W/m²; ✅ Electrical output was stable, with an open-circuit voltage of 32.56 V and a short-circuit current of 0.612 A, demonstrating excellent power generation parameters; ✅ Degradation resistance was outstanding: first-year light-induced degradation was 1.85%, and the average annual power degradation was only 0.48%—both figures surpassing standard limits—with long-term power generation stability verified by a third party. Meanwhile, Guangji Green Energy has completed a comprehensive suite of rigorous reliability tests for its perovskite photovoltaic glass—covering key aspects such as visual inspection, power generation performance verification, environmental aging, mechanical strength, insulation safety, and degradation stability—to provide highly reliable, high-performance perovskite photovoltaic building materials to global BIPV customers.
