How Spatial ALD Shapes Perovskite Performance, Stability, and Cost at Scale

As perovskite solar manufacturing accelerates toward industrial scale, Spatial ALD is becoming a key enabler of high‑performance, stable, and cost‑competitive devices. This presentation highlights how Kalpana Systems’ first commercial roll‑to‑roll Spatial ALD platform addresses critical production challenges—from defect control to encapsulation quality—while delivering the throughput and uniformity required for true gigawatt‑scale manufacturing. We show how Spatial ALD directly enhances device efficiency and durability, lowers total cost of ownership through high uptime and low precursor use, and provides a clear pathway to high‑volume perovskite production. With its commercial system now deployed, Kalpana Systems is setting the benchmark for scalable, industry‑ready roll-to-roll Spatial ALD.
