PEROVSKITE PHOTOVOLTAICS

Two cations make the right layer

Nature Energy volume 7, pages 570–571 (2022)Cite this article

Subjects

All-perovskite tandem devices are promising due to their high efficiency and low cost but their development is hindered by narrow-bandgap absorbers. Now, researchers combine two large organic cations to improve the optoelectronic quality of narrow-bandgap tin–lead perovskites, enabling single-junction and tandem cells with enhanced efficiency and stability.
