S208: ”TOPCon of the Class” with Oliver Schultz-Wittmann of Holosolis

This week on The Solar Journey, Torsten speaks with Oliver Schulz-Wittmann, CTO of Holosolis, a veteran of the solar technological development. With a career spanning innovative startups, major R&D projects, and important roles in solar manufacturing, Oliver has seen a lot!

From humble beginnings analyzing samples for radioactivity post-Chernobyl during his time in civil service, Oliver is currently leading plans to establish a 5 GW solar cell and module manufacturing facility in France. He shares insights into the challenges and opportunities in scaling European solar production and also dives into the evolving role of intellectual property in the solar industry, as well as why he believes nuclear energy cannot compete with the speed, cost, and scalability of renewables.

Drawing from his extensive experience in navigating technological development, market shifts, and startup environments, he reflects, "Just focus on the things you can do. And when you have something, if there's value in it, there will be a way to apply it, to use it. So don't get distracted from all the noise around you."

An inspiring listen for anyone interested in scaling businesses or driving change in renewable energy manufacturing – this conversation is brimming with thoughts on innovation, perseverance, and the future of clean energy in Europe and beyond.

PLUS on this week’s Espresso, Torsten touches base with a solar module maker that is trying to make it in America. Sirius PV is currently ramping a factory in Texas, and CEO Ercan Kalafat provides an update on the company’s progress.
