NTI Nanofilm Showcases Scalable CSS Technology for Perovskite Solar Cells at the 7th Perovskite & Tandem Cell Technology Forum 2025

Changzhou, China - April 16–17, 2025 Last week, industry leaders, researchers, and solar technology pioneers gathered at the 7th Perovskite & Tandem Cell Technology Forum to explore cutting-edge solutions shaping the next generation of photovoltaic innovation. Hosted by ASIACHEM in Changzhou, the forum spotlighted commercial readiness of HJT, perovskite, and tandem cell technologies and addressed urgent manufacturing challenges related to efficiency, stability, and cost.

Representing NTI Nanofilm, Dr. Ng Yan Fong took the stage to share groundbreaking insights into how the company’s Close Space Sublimation (CSS) equipment technology is enabling scalable, high-performance manufacturing of perovskite solar cells.

Enabling Industrial-Scale Perovskite Film Deposition

In his session, Dr. Ng introduced the key advantages of NTI Nanofilm’s CSS approach, a top-down, short-gap deposition method that offers a fast, uniform, and high-efficiency pathway for thin-film growth. Unlike conventional vertical or bottom-up coating systems, CSS minimizes material loss, enhances film crystallinity, and significantly reduces cycle time, making it ideal for industrial-scale production. The system supports:

• High deposition rates of several microns per minute, increasing throughput
• Uniform thin films across large-area substrates
• Low vacuum operation, eliminating the need for complex ultra-high vacuum systems
• High material transfer efficiency, thanks to a gap of just 1–10 mm between source and substrate
• Scalability for large-area module manufacturing
• Proven compatibility with CdTe production lines

Dr. Ng also emphasized how CSS’s design allows for simplified mechanical structure and seamless integration into vacuum-based production lines, key considerations for manufacturers looking to transition from lab-scale to high-volume manufacturing. These attributes make NTI Nanofilm’s CSS system not only a high-performance alternative but also a commercially proven technology with real-world applicability for next-generation solar cell manufacturing.

Accelerating the Commercialization of Perovskite Solar Cells

As the PV industry continues to push for efficiency gains and cost reductions, NTI Nanofilm’s CSS platform stands out as a practical, scalable solution. It addresses critical industry pain points in producing large-area, pinhole-free perovskite films with high crystal quality and long-term stability, an essential step toward broader adoption of tandem and perovskite cell technologies. NTI Nanofilm’s participation at the forum reinforces its commitment to deep-tech innovation, industrial scalability, and collaboration with global clean energy partners. By delivering next-gen coating and equipment solutions, the company continues to shape the future of solar manufacturing.
