The world's first commercial tandem perovskite-silicon module

Today’s mainstream solar photovoltaic technology – silicon – is nearing its practical and economic efficiency limits. Perovskite-silicon tandem technology breaks through this efficiency barrier to deliver the highest-efficiency, most versatile, space and cost-effective type of solar cell in the world. As the next generation of solar PV, this innovation has the potential to transform the economics and accelerate the growth of solar generation applications globally. In 2024, Oxford PV marked a historic milestone by shipping the world’s first commercial perovskite-silicon tandem modules, demonstrating that this breakthrough technology is now commercially viable and ready for large-scale deployment.
This presentation will explore the rapid development and exceptional performance of perovskite-silicon tandems, highlighting recent advancements and charting the roadmap to further improvements. Key challenges such as ensuring long-term durability, scalability, and meeting rigorous environmental standards will be described alongside innovative solutions in processing, materials science, and device architectures to overcome them. A particular emphasis will be placed on scaling and manufacturability, demonstrating how the perovskite cell technology can integrate into existing silicon cell manufacturing process flows and product designs with minimal disruption. Insights from Oxford PV R&D, pilot, production and collaborative industrial initiatives will showcase the readiness of this technology for commercial deployment.
This presentation will provide a vision for how this groundbreaking technology will help drive the next phase of solar energy adoption, shaping a cleaner and more sustainable future.
