Ultra-Thin Lead Sulfide Capping for Stabilizing Tin Halide Perovskite Solar Cells.
Article in Small (Weinheim an der Bergstrasse, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Addressing the inherent instability of tin-based perovskite solar cells (PSCs), a facile approach is introduced to simultaneously enhance their stability and performance. This study demonstrates the implementation of an ultra-thin (≈3 nm) dual-functional lead sulfide (PbS) capping layer, formed via a sequential deposition. This PbS layer serves a critical dual role: first, as a robust protective barrier against oxidation and moisture, effectively mitigating the degradation of the underlying tin-based perovskite; and second, by improving interfacial electronic properties to facilitate efficient charge extraction. Specifically, the PbS layer not only provides conformal coverage and minimizes non-radiative recombination but also acts as an n-type interfacial layer, promoting electron transport. This synergistic effect results in a significant boost in power conversion efficiency (PCE) from 12.0% to 14.4% with an open-circuit voltage of 0.845 V, and exceptional long-term stability with negligible PCE decay after 1600 h in a nitrogen environment. Operando grazing-incidence wide-angle X-ray scattering (GIWAXS) measurements corroborate enhanced structural stability under operating conditions. These findings establish the PbS capping layer as a practical, facile, and highly effective strategy for advancing stable and high-performance tin-based PSCs, paving the way for their viable application in sustainable photovoltaics.
