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.

Evolution of defects during the degradation of metal halide perovskite solar cells under reverse bias and illumination

Zhenyi Ni et al.

Summary: The study reveals the location, mechanisms, and defects involved in the performance degradation of p-i-n perovskite solar cells under illumination or reverse bias. The efficiency decreases over time, yet the introduction of a hole-blocking layer between the layers can improve the reverse-bias stability. Charged iodide interstitial defects within the device layers are observed and found to contribute to efficiency degradation under both light and reverse bias conditions.

Nanoscale Visualization of Photodegradation Dynamics of MAPbI3 Perovskite Films

Nikita A. Emelianov et al.

Summary: In this study, nanoscale visualization of the photochemical degradation dynamics of MAPbI3 was achieved using infrared scattering scanning near-field microscopy combined with complementary analytical techniques. The results showed that light exposure led to a gradual loss of MA+ cations in MAPbI3 films, resulting in the formation of a PbI2 skin with enhanced photoluminescence.
