Volume 41 of our downstream journal, PV Tech Power, is out now and tackles the “hope and hype” of perovskite PV, a technology attracting excitement and scorn in equal measure as it inches ever closer to commercialisation.

Our cover report looks at some of the milestones the technology has achieved, including its first reported commercial deployment earlier this year. We assess whether it has the potential to dethrone crystalline silicon as the PV industry’s go-to technology or whether it will be one technology among many in a more diversified portfolio of solar generation technologies. We also feature a report from VDE Americas exploring the extensive bankability challenges the technology must overcome if it is to achieve widespread adoption.

PV Tech has been running PV ModuleTech Conferences since 2017. PV ModuleTech USA, on 17-18 June 2025, will be our fourth PV ModulelTech conference dedicated to the U.S. utility scale solar sector. The event will gather the key stakeholders from solar developers, solar asset owners and investors, PV manufacturing, policy-making and and all interested downstream channels and third-party entities. The goal is simple: to map out the PV module supply channels to the U.S. out to 2026 and beyond.
