Inspired by the robust gripping mechanism of bird claws, which utilize minimal yet geometrically efficient structures to firmly secure targets, we produce a “molecular claw” strategy at the grain boundaries of the perovskite lattice. This approach introduces a claw-like molecule capable of multisite anchoring at grain boundaries, effectively stabilizing metastable terminal groups and mitigating failure pathways. Perovskite solar cells employing this strategy achieve exceptional efficiency and stability, with a stabilized efficiency of 24.63% compared to 21.08% for control devices, as well as 1400% increased lifetime of T80 compared to control devices.

However, its impact on the rear-side Ag–Si contacts has been overlooked. By investigating LECO, its impact was revealed that electrochemical reduction reaction occurred at the rear-side Ag–Si interface during LECO. This reaction makes it possible for the controlled directional growth of Ag crystallites, thereby optimizing the Ag–Si contact quality.

This study proposes a novel method of fabricating ST crystalline silicon solar cells with average visible transmittance (AVT) controlled via hexagon-arranged microhole patterns using two-step laser processing. The optimal configuration of microholes was evaluated, with the AVT as functions of microhole diameter and distance. The two steps of laser processing, avoiding the shunt problem during cell fabrication with one-step laser to form microholes, were individually performed. Thus, 80% and 20% of the thickness of silicon wafer were respectively removed via melting before and after cell fabrication. The advanced fabrication of a silicon heterojunction solar cell was thus conducted, and a wet procedure was responsible for removing the damage caused by first-step laser processing. Therefore, the performance of the cell mainly depended on the damage due to second-step laser processing. We finally prepared ST silicon solar cells with power conversion efficiency of 10.2% at AVT of 13%, damp-heat endurance, and neutral colors.

A widely adopted strategy for regulating BHJ morphology involves the incorporation of small amounts of additives. However, employing volatile solid additives necessitates precise volatilization control, which remains challenging. While nonvolatile solid additives with high boiling points have been explored, most exhibit large and structurally complex architectures, raising concerns regarding their role in OSCs and their potential impact on charge transport. Thus, a nonvolatile solid additive with both a high boiling point and a simple molecular structure is highly desirable. In this study, 4-bromobiphenyl (BBP), a nonvolatile solid additive with a high boiling point and a simple chemical structure, was incorporated into OSCs to modulate BHJ morphology. The addition of BBP enhanced donor–acceptor miscibility, suppressed excessive aggregation, and promoted a uniform morphology with improved crystallinity. Consequently, the power conversion efficiency significantly increased to 18.11%, surpassing that of OSCs incorporating volatile solid additives while also enhancing long-term stability.

Traditional trial-and-error experimental methods face substantial limitations, including high energy consumption, cost, and time demands, which may not be sufficient for investigating the quantitative relationships between material properties and <i>J</i>_sc in ternary OSCs.

Additionally, three NFA-based ternary OSCs are fabricated and characterized experimentally to validate the predictions made by the proposed model. Using three different NFA-based ternary OSCs as inputs, the model demonstrates good predictive accuracy for <i>J</i>_sc values.
