Solar energy production via photovoltaics is crucial for rapid decarbonization of the global economy. Encouragingly, over 1 TW of cumulative PV capacity has been deployed globally, and this deployment rate continues accelerating as costs drop further. However, silicon PV is nearing practical efficiency limits. This makes perovskite-on-silicon tandem solar cells a highly attractive addition to the existing portfolio of solar energy technologies, promising more than 20% higher power output compared to single-junction silicon.

At Oxford PV, our mission is transitioning this transformative technology from breakthrough to mainstream deployment. In this talk, I will discuss the key opportunities and challenges of commercializing this technology for real-world impact. A central focus will be Oxford PV's multi-dimensional approach to ensuring the long-term performance and reliability of perovskite-based solar cells. This is a critical aspect for eventually scaling this technology to the terawatt level.
