Monolithic all-perovskite tandem solar cells offer an avenue to increase power conversion efficiency beyond the limits of single-junction cells. It is an important priority to unite efficiency, uniformity and stability, yet this has proven challenging be
All-perovskite tandem solar cells promise higher power-conversion efficiency (PCE) than single-junction perovskite solar cells (PSCs) while maintaining a low fabrication cost. However, their performance is still largely constrained by the subpar performance of mixed lead-tin (Pb-Sn) narrow-bandgap ...
Among them, all-perovskite tandem solar cells exhibit unique advantages of both low-cost fabrication and high efficiency. They have advanced rapidly in these years, due to the realization of stable and efficient narrow-bandgap perovskites. In this work, we review the development of monolithic all-...
Tandem solar cells use two absorbers instead of one, each specializing in a region of the solar spectrum, raising the theoretical efficiency to 46%2. This helps reduce the energy lost to electron-phonon scattering events (thermalization), the most prominent intrinsic loss mechanism in solar cells...

The flexible and all-perovskite tandem solar cells devised by the researchers have a carefully studied design and composition. When their frontal cell, comprised of a perovskite film with a wide bandgap, is illuminated by the sun, it absorbshigh energy photons. Its posterior cell, on the other...
All-perovskite tandem solar cells hold the promise of surpassing the efficiency limits of single-junction solar cells; however, until now, the best-performing all-perovskite tandems have exhibited lower certified efficiency than have single-junction perovskite solar cells. A thick mixed Pb-Sn narrow...
The fabrication of scalable all-perovskite tandem solar cells is considered an attractive route to commercialize perovskite photovoltaic modules 1 . However, the certified efficiency of 1-cm 2 -scale all-perovskite tandem solar cells lags behind their small-area (approximately 0.05-cm 2 ) counterparts...
