Tempress had developed an alternative atmospheric process called ‘High Density POCl3’ (Phosphorus Diffusion), using improved chemistry and hardware upgrades to provide improved uniformity and higher cell efficiencies via formation of the emitter.

Fokko Pentinga, chief exeutive of Amtech, commented: “After Tempress' successful implementation of approximately 400MW of HD-POCl3 systems at a top-tier Taiwanese cell producer, we are proud to announce a repeat order from this same Taiwanese customer and a new order from a new customer in Taiwan. In addition, we successfully installed approximately 800MW of our atmospheric high-throughput diffusion systems at a leading Chinese solar cell and module manufacturer. One of the key differentiators is the integrated compact automation which seamlessly matches the high output of the HD-POCl3. This system is delivered and installed by another subsidiary of Amtech, R2D Automation.”

PV Tech has been running an annual PV CellTech Conference since 2016. PV CellTech USA, on 7-8 October 2025 is our third PV CellTech conference dedicated to the U.S. manufacturing sector. The events in 2023 and 2024 were a sell out success and 2025 will once again gather the key stakeholders from PV manufacturing, equipment/materials, policy-making and strategy, capital equipment investment and all interested downstream channels and third-party entities. The goal is simple: to map out PV manufacturing in the U.S. out to 2030 and beyond.
