All-perovskite tandem solar cells with 24.2% certified efficiency and area over 1 cm2 using surface-anchoring zwitterionic antioxidant

TL;DR: Xiao et al. as mentioned in this paper used strongly reductive surface-anchoring zwitterionic molecules to suppress Sn2+ oxidation and passivate defects at the grain surfaces in mixed lead-tin perovskite films, enabling an efficiency of 21.7% (certified 20.7%).

Understanding the rate-dependent J–V hysteresis, slow time component, and aging in CH3NH3PbI3 perovskite solar cells: the role of a compensated electric field

TL;DR: In this paper, the rate-dependent hysteresis seen in current-voltage scans of CH3NH3PbI3 perovskite solar cells is related to a slow field-induced process that tends to cancel the electric field in the device at each applied bias voltage.

Hysteresis and transient behavior in current–voltage measurements of hybrid-perovskite absorber solar cells

TL;DR: In this article, the authors observe slow transient effects causing hysteresis in the current-voltage characterization of hybrid organo-metal halide perovskites that can lead to an over- or underestimation of the solar cell device efficiency.

Organometal Halide Perovskite Solar Cell Materials Rationalized: Ultrafast Charge Generation, High and Microsecond-Long Balanced Mobilities, and Slow Recombination

TL;DR: Photoluminescence, transient absorption, time-resolved terahertz and microwave conductivity measurements are applied to determine the time scales of generation and recombination of charge carriers as well as their transport properties in solution-processed CH3NH3PbI3 perovskite materials to unravel the remarkable intrinsic properties of the material.
