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...
