TL;DR: In this paper, the authors improved the efficiency of monolithic, two-terminal, 1-cm2 perovskite/silicon tandems to 23.6% by combining an infrared-tuned silicon heterojunction bottom cell with the recently developed caesium formamidinium lead halide pervskite.

TL;DR: This device architecture and materials set will enable “all-perovskite” thin-film solar cells to reach the highest efficiencies in the long term at the lowest costs.
Journal ArticleDOI

TL;DR: The addition of guanidinium thiocyanate (GuaSCN) resulted in marked improvements in the structural and optoelectronic properties of Sn-Pb mixed, low-band gap perovskite films, enabling the demonstration of >20% efficient low–band gap PSCs.
Journal ArticleDOI

TL;DR: A method for incorporating chloride is reported that allows for fabrication of stable triple-halide perovskites with a band gap of 1.67 electron volts and a factor of 2 increase in photocarrier lifetime and charge-carrier mobility that resulted from enhancing the solubility of chlorine by replacing some of the iodine with bromine to shrink the lattice parameter.
