PV manufacturing equipment specialist INDEOtec SA has been awarded a grant from the SWISS Commission for Technology and Innovation (CTI) to further develop its OCTOPUS deposition platform for heterojunction solar cells in partnership with Swiss research partner, CSEM.

INDEOtec said the funding was in the 'single-digit million Swiss Franc' range and would support further validation of its OCTOPUS II / PECVD-PVD cluster system for double-sided deposition, enabled by its ‘Mirror Reactor’ design that offers lower processing costs and higher conversion efficiencies for heterojunction solar cells.

Dr. Omid SHOJAEI, CEO of INDEOtec SA said, “For high-efficiency cells the heart of the system is the proprietary Mirror Reactor concept for the thin-film passivation layer deposition from the bottom and the top. We already demonstrated superior results and the proper functionality of the Mirror Reactor, and we would like to strengthen the confidence in the technology by a number of additional test series and the achievement of high cells efficiency before the application in our mass production tool.”

INDEOtec noted that the R&D project with CSEM would target the ability to manufacture in typical volume processing environments cell precursors that would yield to >23% efficiency levels with low thickness non-uniformity for the deposited thin films of < 5%.

The company had previously sold its tools to other R&D facilities in Europe and the US.

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.
