Abstract: Non-radiative recombination is a key factor restricting photocatalytic efficiency, which leads to the rapid annihilation of photogenerated carriers through deep-level defect centers. Shallow-level defects can suppress non-radiative recombination through a unique carrier capture-release mechanism. Herein,… read more here.

DOI: 10.1038/s41467-024-50016-6
Abstract: The power conversion efficiency of perovskite solar cells continues to increase. However, defects in perovskite materials are detrimental to their carrier dynamics and structural stability, ultimately limiting the photovoltaic characteristics and stability of perovskite solar… read more here.
