I will discuss progress in inverted perovskite photovoltaics, an architecture pursued in part for its enablement of more thermally-stable and operationally-stable photovoltaic performance. I will discuss the use of 2D/3D heterostructures in the context of the inverted architecture, with a focus on removing the barrier to electron extraction at the 2D/3D interface in such devices, something achieved through the design of reduced-dimensional layers and their materials processing. I will update on the NREL-certified efficiency of such devices and on ISOS-L3 accelerated aging. I will conclude with a discussion of further steps forward for this area, including in the context of performance and operating stability at accelerated-ageing temperatures.
