Circularity in Perovskite-Based Tandem Photovoltaics for Terawatt-Scale Deployment

Abderrahime Sekkat, Jenny Baker, Matt Burnell, Robert L. Z. Hoye, Ruy S. Bonilla, Shiling Dong, Tapas Mallick

Metal-halide perovskite tandem photovoltaics promise higher efficiencies alongside intrinsic circularity benefits that simplify recycling compared to crystalline silicon.

Claims

C1strongest claim

MHP-based tandem PVs not only promise higher power conversion efficiencies than single-junction c-Si devices, but also offer intrinsic advantages for circularity, including simpler device architectures, low-temperature processing, and more accessible materials recovery routes.

C2weakest assumption

That the listed intrinsic advantages for circularity can be realized at commercial scale while maintaining performance, and that policy frameworks will provide effective incentives across the device lifecycle.

C3one line summary

Perovskite-based tandem photovoltaics have intrinsic circularity advantages over silicon panels due to simpler architectures and easier material recovery, but require targeted solutions for scarce materials, scalable recycling, lead sequestration, and supportive policies to enable terawatt-scale use
