Perovskite Industrialization: How to Overcome the Critical Barrier of Water and Oxygen

Perovskite solar cells are advancing toward industrialization at an unprecedented pace. Efficiency records for large-area tandem cells are being broken one after another, conversion efficiencies of commercial-sized modules continue to reach new heights, and leading companies are rolling out pilot lines and mass production projects in quick succession. These developments send a clear signal: perovskite technology has officially moved beyond the "efficiency race" in laboratories and entered the critical phase of "stable mass production" on production lines.

However, perovskite has an inherent Achilles' heel—it is extremely sensitive to water, oxygen, and impurities.

The light-absorbing layer of perovskite materials is highly vulnerable to water and oxygen. Exposure to even trace amounts of water in air causes rapid decomposition, leading to complete structural collapse of the material. Minor fluctuations in oxygen levels and temperature also pose significant challenges to the long-term stability of devices. Any slight environmental variation during the three core processes—coating, etching, and encapsulation—can directly impact the conversion efficiency and service life of the devices. This is one of the core reasons why the high efficiencies achieved with small laboratory cells are difficult to fully replicate in mass-produced modules.

This raises a pivotal question that determines the success of industrialization: Who can provide a stable and reliable inert atmosphere environment for the entire manufacturing process?

Glove Boxes: The "Environmental Cornerstone" of Perovskite Preparation

In perovskite solar cell manufacturing, glove boxes play a crucial role as "environmental gatekeepers". By filling with high-purity inert gas, they create a clean space with water and oxygen content below 1 ppm, effectively preventing perovskite materials from degradation due to water and oxygen exposure during preparation, storage, and testing.

Film formation quality is equally sensitive to environmental cleanliness, as tiny particles can directly cause defects in thin films. Vigor Technology has developed a clean environment specifically tailored for the perovskite industry that minimizes impact on film formation, achieving ISO Class 2 cleanliness to effectively remove micro-particles. Meanwhile, sealing technology is the key to maintaining a stable environment. Vigor Technology adopts its patented leak-free sealing technology, forming a "double insurance" protection with double-layer sealing rings to block external water and oxygen penetration at the molecular level. With a leakage rate as low as <0.001 vol%/h, it can stably maintain water and oxygen content below 1 ppm for long periods, not only extending the equipment regeneration interval but also reducing the impact of environmental fluctuations on the continuity of research and production.

In addition, glove boxes effectively isolate organic solvent vapors and lead-based by-products generated during perovskite material preparation, providing reliable safety protection for frontline researchers and production personnel. A stable and controllable inert atmosphere environment minimizes the interference of water and oxygen on the film formation process, preventing decomposition or crystalline defects in the light-absorbing layer caused by water and oxygen exposure, thus ensuring device performance and preparation repeatability from the source.

From Single Equipment to Full-Line Integration: One-Stop Solutions for the Mass Production Era

As perovskite moves toward industrialization, standard single glove boxes can no longer meet production demands. The core equipment for perovskite battery manufacturing includes coating equipment, laser equipment, and encapsulation equipment. To effectively improve device yield, it is necessary to integrate all process segments into a unified inert atmosphere environment.

Currently, Vigor Technology provides full-chain solutions covering R&D, pilot lines, and mass production levels, implementing "integrated management" of various system equipment. It can integrate common modules such as VCD, PVD, ALD, coaters, evaporation systems, solar simulators, annealing stations, and balances, and customize semi-automated or fully automated highly integrated solutions on demand, significantly saving labor and management costs and reducing adaptation risks between different equipment.

Its independently developed production lines adopt a modular design with full interconnection across the entire line, and can also be customized to integrate various equipment such as laser cutters, liquid injection machines, weighing equipment, and drying systems according to process requirements. For the core demand of large-area mass production, its large-scale dry rooms achieve a dew point as low as -78°C and oxygen content <1 ppm, creating an environment standard equivalent to that of glove boxes. Meanwhile, compared with traditional dehumidifier solutions, it achieves an 85% energy saving, making it more suitable for large-scale mass production scenarios and truly realizing cost reduction and efficiency improvement.

Environmental Control: From Hidden Cost to Tangible Benefit

In the process of perovskite industrialization, the value of inert atmosphere environmental control has long been underestimated. In fact, when the entire process flow—including coating, annealing, etching, and encapsulation—is carried out in a stable and controllable inert atmosphere, the interference of environmental factors on device performance is systematically eliminated. The resulting benefits are clear: improved process repeatability, reduced defect rates, and lower material waste, which ultimately translate directly into simultaneous increases in product yield and equipment utilization. This is the key logic behind environmental control transforming from a mere "support condition" to a "benefit lever".

From the precise protection of single glove boxes at the laboratory scale, to process parameter locking in the pilot phase, and then to full-process atmosphere integration in mass production lines, environmental control runs through every critical node of perovskite from R&D to commercialization. Today, leading companies in the industry have gradually reached a consensus: a reliable atmosphere environment management system is the core infrastructure that breaks down the barrier between "high efficiency" and "high stability".

Conclusion

The future of perovskite has arrived. As the industry's focus shifts from "can we make it?" to "can we produce it stably?", environmental control systems are no longer supporting players in industrialization but critical infrastructure that determines success or failure. It is believed that with the continuous iteration and popularization of professional inert atmosphere solutions, the entire industry will eventually successfully cross the critical threshold of water and oxygen, driving perovskite photovoltaic technology to truly achieve large-scale commercial application.
