Performance and stability analysis of all-perovskite tandem photovoltaics in light-driven electrochemical water splitting by Junke Wang, Bruno Branco, Willemijn H. M. Remmerswaal, Shuaifeng Hu, Nick R. M. Schipper, Valerio Zardetto, Laura Bellini, Nicolas Daub, Martijn M. Wienk, Atsushi Wakamiya, Henry J. Snaith, René A. J. Janssen

“…Here we report a laboratory-scale solar-assisted water-splitting system using an electrochemical flow cell and an all-perovskite tandem solar cell. We begin by treating the perovskite surface with a propane-1,3-diammonium iodide solution that reduces interface non-radiative recombination losses and achieves an open-circuit voltage above 90% of the detailed-balance limit for single-junction solar cells between the bandgap of 1.6–1.8 eV. …”
