All-perovskite tandem solar cells with improved grain surface passivation

Renxing Lin et al.

Summary: Researchers have developed ammonium-cation-passivated Pb-Sn perovskites with long diffusion lengths, enabling high-efficiency all-perovskite tandem solar cells. By enhancing the adsorption of the passivator using a stronger surface-passivator interaction, the carrier diffusion length within Pb-Sn perovskites is doubled, resulting in an efficiency of over 22%. The certified efficiency of 26.4% achieved in the all-perovskite tandem solar cells exceeds that of the best-performing single-junction perovskite solar cells.

Prospects for metal halide perovskite-based tandem solar cells

Rui Wang et al.

Summary: Metal halide perovskite photovoltaics have made significant progress in the past decade, particularly in increasing the efficiency of single-junction perovskite solar cells from 3.8% to 25.5%. The broad bandgap tunability of perovskites can potentially overcome the efficiency limits of traditional solar cells, and the development of tandem solar cells pairing perovskite with other mature photovoltaic technologies shows promising prospects.
