“…Gold (Au) nanoclusters exhibit unique optical, electrochemical properties and size tunable physicochemical properties, and these are closely related to their surface ligands which have been proved to effectively facilitate the carrier transfer in PSCs. [ 24,25 ] Proteins are commonly utilized to modify metal nanoparticles owing to their good biocompatibility, multifunctional properties, and various chemical reaction groups. Bovine serum albumin (BSA) is the most prevalent protein, comprising abundant reaction groups, such as amino groups, and can effectively passivate defects in perovskite.…”

The heterogeneity of perovskite film crystallization along the vertical direction leads to voids and traps at the buried interfaces, hampering both efficiency and stability of perovskite solar cells. Here, bovine serum albumin‐functionalized Au nanoclusters (ABSA), combined with heavy gravity, high surface charge density, and strong interactions with the electron transport layer, are designed to reconstruct the buried interfaces for not only high‐quality crystallization, but also improved carrier transfer. The ABSA macromolecules with amine function groups and larger surface charge density interact with the perovskite to improve the crystallinity, and gradually migrate towards the buried interface, healing the defective voids, hence suppressing surface recombination velocity from 3075 to 452 cm s−1. The healed buried interface and the higher surface potential of ABSA‐modified TiO2 lead to improved carrier extraction at the interface. The resulting solar cell attains a power conversion efficiency of 25.0% with negligible hysteresis and remarkable stability, maintaining 92.9% of their initial efficiency after 3200 h of exposure to the ambient atmosphere, they also exhibit better continuous irradiation stability compared to control devices. These findings provide a new metal‐protein complex to eliminate the deleterious voids and defects at the buried interface for improved photovoltaic performance and stability.

Halide perovskite is an emerging material with excellent optoelectronic properties, and also widely used in neuromorphic devices. Recently, halide perovskite has been redefined as exhibiting extraordinary multifunction, e.g., photoferroelectricity. Herein, this work employs a composite material consisting of halide perovskite and organic ferroelectric material to develop a new photoferroelectric synapse, and the photoferroelectricity and some synaptic plasticity are investigated. By the corresponding test analysis, it is demonstrated that photoelectricity and ferroelectricity can reinforce each other in this photoferroelectric composite material. Versatile synaptic behaviors of the nervous system, including paired‐pulse facilitation/paired‐pulse depression, post‐tetanic potentiation /post‐tetanic depression, and spiking‐rate‐dependent plasticity, are successfully simulated. Particularly, the classical conditioning in Pavlov's dog experiment can be replicated in the photoferroelectric synapse to realize the learning function of the brain, including memory loss and recovery. This work could be conducive to the application of multifunctional perovskite materials in synapse devices and neuromorphic computing.
