Negative Capacitance and Inverted Hysteresis: Matching Features in Perovskite Solar Cells

Agustin O. Alvarez, Ramon Arcas, Clara A. Aranda +4

Negative capacitance at the low-frequency domain and inverted hysteresis are familiar features in perovskite solar cells, where the origin is still under discussion. Here we use Im…

Crystal orientation and grain size: do they determine optoelectronic properties of MAPbI3 perovskite?

Loreta A. Muscarella, Eline M. Hutter, Sandy Sanchez +5

It is thought that growing large, oriented grains of perovskite can lead to more efficient devices. We study MAPbI3 films fabricated via Flash Infrared Annealing (FIRA) consisting…

The perovskite/transport layer interfaces dominate non-radiative recombination in efficient perovskite solar cells

Martin Stolterfoht, Pietro Caprioglio, Christian M. Wolff +12

Charge transport layers (CTLs) are key components of diffusion controlled perovskite solar cells, however, they can induce additional non-radiative recombination pathways which lim…
