BGI GenomicsRegulating high-concentration precursor crystallization to reduce photon loss in bifacial perovskite solar cells
Science China PressPeer-Reviewed Publication
This study identifies photon loss as the key bottleneck limiting the efficiency of bifacial perovskite solar cells (Bi-PSCs). The researchers proposed a strategy for constructing high-quality thick films by regulating precursor crystallization, which reduces current loss to an unprecedented 1.67 mA cm-2 and achieves a record-breaking power conversion efficiency. Meanwhile, the long-term stability of the devices is significantly enhanced.

Uncovering the rock record of Earth’s earliest continental crust
Science China PressPeer-Reviewed Publication
In a paper published in National Science Review, scientists used machine learning to reconstruct the geochemical composition of the Hadean continental crust. Based on Jack Hills zircons, the study reveals a felsic crust dominated by TTGs and potassic granites, formed through partial melting of mafic protocrust during crustal thickening. The results provide new constraints on early Earth’s tectonic evolution.

Acoustic trick mirrors quantum paradox: Anti-Klein tunneling confirmed
Science China PressPeer-Reviewed Publication
In this breakthrough acoustic experiment, researchers have directly observed anti-Klein tunneling—a quantum-like phenomenon where chiral sound waves are entirely blocked by a barrier. Using a tunable bilayer phononic crystal, the team demonstrated switchable transitions between full transmission and total reflection, mimicking quantum paradoxes with sound. This work confirms a long-standing theoretical prediction and opens new possibilities for topological wave control and quantum-inspired acoustic devices.

"Magic molecules" reduce transistor resistance by 16 times, paving way for flexible electronics
Science China PressPeer-Reviewed Publication
Magic fluorinated molecules like PFBT drastically reduce contact resistance by a factor of 16 in flexible organic transistor, diminish energy barriers by 73%, and enhance operational metrics. Derived from in-situ chemical reactions at metal-organic semiconductor buried interfaces, this breakthrough eliminates interfacial trap states and mitigates Fermi-level pinning. This innovation sparks visions of sleek bendable screens and intuitive wearable technology, reshaping flexible electronics with elegance and precision.

Intercellular crosstalk within human preimplantation lineages regulates trophectoderm specification
Science China PressPeer-Reviewed Publication
In a study published in Science Bulletin, researchers from Tongji University led by Professors Yixuan Wang and Shaorong Gao constructed a novel in vitro model simulating the human preimplantation epiblast (EPI), primitive endoderm (PrE), and trophectoderm (TE) lineages. Through single-cell transcriptomic analysis and intercellular communication inference using CellChat toolkit, the team delineated the cell-cell communication landscape among tri-lineages. Notably, they highlighted the critical role of secreted NRG signaling from EPI to TE, mediated by NRG1-ERBB3 axis, in regulating trophectoderm specification through the intracellular effector TFAP2C—a signaling axis validated in both trophectoderm induction system and human blastocyst development.
