In contrast to conventional (n–i–p) perovskite solar cells (PSCs), inverted (p–i–n) PSCs offer enhanced stability and integrability with tandem solar cell architectures, which have garnered increasing interest. However, p–i–n cells suffer from energy level misalignment with transport layers, imbalanced transport of photo-generated electrons and holes, and significant defects with the perovskite films. Here we introduce tris(2,4,6-trimethyl-3-(pyridin-3-yl)phenyl)borane (3TPYMB), a nonionic n-type molecule that, through hydrogen bonding and Lewis acid–base reactions with perovskite surfaces or grain boundaries, enables in situ modulation of perovskite energetics, effectively mitigating the key challenges of p–i–n PSCs. The p–i–n PSCs incorporating 3TPYMB achieve a certified quasi-steady-state power conversion efficiency of 24.55 ± 0.33%, with a reverse scan efficiency of 25.58%. They also exhibit exceptional stability, with unencapsulated devices retaining 97.8% of their initial efficiency after 1,800 h of continuous operation at maximum power point under N2 atmosphere, 1 sun illumination and 60 °C conditions. The introduction of 3TPYMB, an n-type molecule into inverted perovskite solar cells, enables a power conversion efficiency of 25.6%, with devices maintaining up to 98% of the initial efficiency after 1,800 h of operation.

Kerr-induced synchronization (KIS) provides a key tool for the control and stabilization of a dissipative Kerr soliton (DKS) frequency comb, enabled by the capture of a comb tooth by an injected reference laser. Efficient KIS relies on large locking bandwidth, meaning both the comb tooth and intracavity reference power need to be sufficiently large. Although KIS can theoretically occur at any comb tooth, large modal separations from the main pump to achieve large optical frequency division factors are often difficult or unfeasible due to cavity dispersion. While tailoring the dispersion to generate dispersive waves can support on-resonance KIS far from the main pump, this approach restricts synchronization to specific wavelengths. Here we demonstrate an alternative KIS method that allows efficient synchronization at arbitrary modes by multi-pumping a microresonator. This creates a multicolour DKS with a main and an auxiliary comb, the latter enabling the creation of a synthetic dispersive wave. As cross-phase modulation leads to a unique group velocity for both the soliton comb and the auxiliary comb, repetition rate disciplining of the auxiliary comb through KIS automatically controls the DKS microcomb. We explore this colour-KIS phenomenon theoretically and experimentally, showing control and tuning of the soliton microcomb repetition rate, resulting in optical frequency division independent of the main pump noise properties. Generalizing the ‘Kerr-induced synchronization’ concept by means of tailoring the synchronization at arbitrary modes allows to lock and control the repetition rate of a dissipative Kerr soliton frequency comb generated in a silicon nitride microring resonator.
克尔诱导同步（KIS）是控制和稳定耗散克尔孤子（DKS）频率梳的关键工具，通过注入参考激光器捕捉梳齿来实现。高效的 KIS 依赖于较大的锁定带宽，这意味着梳齿和腔内参考功率都需要足够大。虽然理论上 KIS 可以发生在任何梳齿上，但由于腔体色散的原因，要实现大的光频分频系数，通常很难或无法实现与主泵浦的大模态分离。虽然调整色散以产生色散波可以支持远离主泵浦的共振 KIS，但这种方法将同步限制在特定波长上。在这里，我们展示了另一种 KIS 方法，即通过多泵浦微谐振器实现任意模式的高效同步。这就产生了具有主梳和辅助梳的多色 DKS，后者能够产生合成色散波。由于交叉相位调制会导致孤子梳状波和辅助梳状波具有独特的群速度，因此通过 KIS 对辅助梳状波的重复率进行调节，就能自动控制 DKS 微梳状波。我们从理论和实验上探讨了这种彩色 KIS 现象，结果表明，对孤子微梳重复率的控制和调整，导致了独立于主泵浦噪声特性的光学频率划分。

An outstanding challenge for deployable quantum technologies is high-resolution laser spectroscopy at the specific wavelengths of ultranarrow transitions in atomic and solid-state quantum systems. Here we demonstrate a highly flexible approach to high-resolution spectroscopy for quantum technologies across a broad range of wavelengths, through the synergistic combination of fine-tooth electro-optic frequency combs and efficient Kerr nonlinear nanophotonics. We show that such fine-tooth combs, which provide simultaneous high spectral and temporal resolution in atomic spectroscopy, undergo coherent spectral translation with essentially no efficiency loss through third-order optical parametric oscillation (OPO) in a silicon-nitride microring. This enables nearly a million comb pump teeth, separated by a 1 kHz spacing, to be translated onto signal and idler beams that can be located across a broad range of wavelengths in the visible and short near-infrared. The generated wavelengths are subject to OPO phase and frequency-matching conditions that are highly controllable through nanophotonic dispersion engineering, and in the current implementation span between 589 and 1,150 nm, with both the electro-optic comb generation process and its spectral translation not introducing appreciable broadening to the pump laser linewidth. We further demonstrate the application of this approach to quantum systems by performing sub-Doppler spectroscopy of the hyperfine transitions of Cs atomic vapour with our electro-optically driven Kerr nonlinear light source. The generality, robustness and agility of our approach, as well as its compatibility with photonic integration, are expected to lead to its widespread applications in areas such as quantum sensing, telecommunications and atomic clocks. A nonlinear nanophotonic resonator is used to spectrally translate an electro-optic frequency comb to a controllable set of wavelengths between 600 nm and 1,050 nm, with comb properties that are advantageous for high-resolution spectroscopy preserved.

Time-programmable frequency combs enable new measurement paradigms for dual-comb spectroscopy (DCS) that are free of many of the constraints found in traditional DCS. As opposed to fixing the repetition rate offset between combs, free-form DCS uses full control of the temporal offset between the dual-comb pulse trains, thereby enabling user-selectable sampling patterns that optimize resolution, signal-to-noise ratio, species selectivity or acquisition time. Here we show that free-form DCS enables compressive sensing and demonstrate compression factors of up to 155, with an up to 60-fold reduction in acquisition time, while maintaining identical spectral point spacing and comparable signal-to-noise ratio to traditional DCS. We also demonstrate molecular recurrence sampling (an extreme case of compressive sensing) for methane detection at 22× higher sensitivity than traditional DCS at the cost of requiring a priori knowledge of the probed species. Finally, free-form DCS can enable fast species-selective imaging since its radio frequency signal is narrow band, in contrast to traditional DCS, and therefore compatible with limited camera read out rates. We demonstrate imaging of methane plumes across a 128 × 64-pixel focal plane array at a 250 Hz rate. In the future, this flexible free-form approach can enable applications ranging from rapid open-path spectroscopy to nonlinear multidimensional comb-based spectroscopy. By incorporating time-programmable frequency combs, free-form dual-comb spectroscopy enables compressive sensing at factors of up to 155, with a corresponding reduction in acquisition time without sacrificing spectral resolution.

Circularly polarized phosphorescence (CPP) is a spin-forbidden radiative process, and its underlying mechanism is not comprehensively understood, mainly due to the limited examples of efficient triplet emission from small chiral organic molecules with well-defined structures. Here we investigate a pair of chiral enantiomers, R- and S-BBTI, that feature highly distorted spiral ring-locked heteroaromatics with heavy iodine atoms. These chiral molecules are found to exhibit large dissymmetry factors up to 0.013 and emit near-infrared CPP with an efficiency of 4.2% and a lifetime of 119 μs in dimethyl sulfoxide solution excited by ultraviolet irradiation. Their crystals show efficient CPP with 7.0% quantum efficiency and a lifetime of 166 μs. Extensive experimental chiroptical investigations combined with theoretical calculations reveal an efficient spin-flip process that modulates the electron and magnetic transition dipole moments to enhance CPP performance. Moreover, the phosphorescence of R/S-BBTI is oxygen-sensitive and photoactivatable in dimethyl sulfoxide. Therefore, R/S-BBTI can be applied for hypoxia imaging in cells and tumours, expanding the application scope of CPP materials. Two chiral enantiomers, R- and S-BBTI, are found to efficiently emit near-infrared circularly polarized phosphorescence with a large dissymmetry factor of 0.013 in dilute solutions.

Modern imaging technologies are widely based on classical principles of light or electromagnetic wave propagation. They can be remarkably sophisticated, with recent successes ranging from single-molecule microscopy to imaging far-distant galaxies. However, new imaging technologies based on quantum principles are gradually emerging. They can either surpass classical approaches or provide novel imaging capabilities that would not otherwise be possible. Here we provide an overview of the most recently developed quantum imaging systems, highlighting the nonclassical properties of sources, such as bright squeezed light, entangled photons and single-photon emitters that enable their functionality. We outline potential upcoming trends and the associated challenges, all driven by a central enquiry, which is to understand whether quantum light can make visible the invisible. This Review provides an overview of the most recently developed quantum imaging systems, highlighting the nonclassical properties of sources, such as bright squeezed light, entangled photons and single-photon emitters that enable their functionality.
