Researchers develop synergistic additives for scalable slot-die-coated perovskite photovoltaics

A research team led by Professor Yang Dong from the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences, in collaboration with Dalian Jiaotong University, has developed a synergistic additive strategy for large-area. The science-journalism coverage adds useful context, while the strongest evidential footing still comes from the underlying data, papers or institutional documentation.

It is relevant because physics only takes a result seriously when the measurement chain remains robust under scrutiny. Experimental particle physics and precision metrology both operate in regimes where the signal sits far below the background noise, and where systematic uncertainties can mimic new physics if not controlled rigorously. The history of the field contains numerous anomalies that generated theoretical excitement before better data showed them to be artifacts, and it also contains genuine discoveries that were initially dismissed as noise. The difference is almost always resolved by independent replication with different instruments and different systematics.

Through these complementary effects, the team extended the processing window for uniform perovskite crystallization to more than 100 seconds. The small-area perovskite solar cells delivered a power conversion efficiency (PCE) of 26.16%.

A large-area module with an active area of 54.80 cm² reached a PCE of 22.70%, substantially higher than the 15.8% of the control module. Unencapsulated devices retained 97.76% of their initial efficiency after 1, 300 hours of continuous maximum-power-point tracking under AM 1.5G illumination at 65°C.

The broader interest lies as much in the method as in the headline number, because a durable measurement procedure can travel farther than a single result. When experimental physicists develop a technique that achieves new sensitivity or controls a previously uncharacterized systematic, that methodological contribution persists even if the specific measurement is later revised. This is one reason why precision physics experiments often generate long-term value that is not immediately visible in the original publication.

By comparison, control devices retained only 65.86% under the same conditions. Lianjie Duan et al, Processing Window Expansion Enables Uniform Crystallization in Scalable Ambient‐Fabricated Perovskite Photovoltaics, Advanced Materials (2026).

Because this item comes through Phys. org Chemistry as science journalism, it should be treated as contextual reporting rather than primary evidence. Good science reporting can identify why a result matters, connect it to the wider literature and make technical work readable, but the decisive evidence remains in the original paper, dataset, mission release or technical record. That distinction is especially important when a story is later repeated by aggregators, because repetition increases visibility, not evidential strength.

The next step is more measurement, tighter systematic control and scrutiny from groups whose experimental setups are genuinely independent. In experimental particle physics and precision metrology, the threshold for a discovery claim is a five-sigma excess surviving multiple analyses; an intriguing signal at lower significance is a reason to run more experiments, not a reason to revise the textbooks. Next-generation experiments currently under construction or commissioning will revisit several of the open questions that give the current result its context.
