Herein, we propose the use of a volatile heterocyclic compound called 2-thiopheneacetic acid (TPA) as a pre-buried additive in the buried interface to achieve cross-layer all-interface defect passivation through an in situ bottom-up infiltration diffusion strategy.

The buried interface in the perovskite solar cell (PSC) has been regarded as a breakthrough to boost the power conversion efficiency and stability. However, a comprehensive manipulation of the buried interface in terms of the transport layer, buried interlayer, and perovskite layer has been largely overlooked.
Conclusion In summary, a comprehensive buried interface passivation strategy was presented for highly efficient n-i-p perovskite photovoltaics by introducing CAHC into the buried interface. This remarkable approach significantly mitigates various defects at the buried interface rather than the previously focused single-type defect passivation.
Buried-interface engineering is crucial to the performance of perovskite solar cells. Self-assembled monolayers and buffer layers at the buried interface can optimize charge transfer and reduce recombination losses. However, the complex mechanisms and the difficulty in selecting suitable functional groups pose great challenges.
In essence, this work gives an outstanding buried passivation strategy for high-performance perovskite photovoltaics and shows the benefits of comprehensive buried passivation, providing a feasible solution for the breakthrough of PSCs in the future.
