Inspired by the success of CH-series acceptors, a small-molecular acceptor, CH-Tz was reported by adopting a new conjugationextended electron-deficient unit([1,2,5]thiadiazolo[3,4-b]pyrazine) on the central core. Owing to the enhanced inter-/intramolecular interactions, CH-Tz exhibited near-infrared absorption and an effective three-dimensional molecular packing network in its single crystal. When blended with polymer donor PM6, the binary device achieved a high power conversion efficiency(PCE) of 18.54%, with a notable short-circuit current density(J_(sc)) of 27.54 m A cm-2and an excellent fill factor(FF) over 80%,which can be partly ascribed to the balanced charge transport properties in the blend film. After employing D18-Cl as the third component, an enhanced PCE of 18.85% was achieved due to a more obvious fiber network. Impressively, the CH-Tz-based OSC devices show excellent thermal stability and thickness insensitivity. Record-breaking Jscof 28.92 m A cm-2was reached for PM6:D18-Cl:CH-Tz ternary device with a thickness of 560 nm. Besides, CH-Tz shows potential in fabricating multicomponent high-performance organic solar cells, where over 19% efficiency could be realized in the quaternary device. Our work advances the strong influence of electron-deficient central units on molecular photovoltaic properties and guides the design of acceptors for stable and large-thickness organic solar cells.

The interaction between sites A, B and X with passivation molecules is restricted when the conventional passivation strategy is applied in perovskite（ABX3） photovoltaics. Fortunately, the revolving A-site presents an opportunity to strengthen this interaction by utilizing an external field. Herein, we propose a novel approach to achieving an ordered magnetic dipole moment, which is regulated by a magnetic field via the coupling effect between the chiral passivation molecule and the A-site（formamidine ion） in *** strategy can increase the molecular interaction energy by approximately four times and ensure a well-ordered molecular arrangement. The quality of the deposited perovskite film is significantly optimized with inhibited nonradiative recombination. It manages to reduce the open-circuit voltage loss of photovoltaic devices to 360 mV and increase the power conversion efficiency to 25.22%. This finding provides a new insight into the exploration of A-sites in perovskites and offers a novel route to improving the device performance of perovskite photovoltaics.

锂掺杂有利于提高铜锌锡硫硒薄膜太阳电池的性能.然而,传统旋涂含锂前驱体溶液的掺杂策略在前驱膜的逐层沉积过程中,由于锂的再溶解而导致大量的锂流失.在本工作中,我们通过刮涂法在柔性钼箔衬底上制备了铜锌锡硫硒薄膜,实现锂的有效掺杂,并进一步研究了锂掺杂对器件性能的影响.随着锂掺杂含量的增加,吸收层晶粒尺寸变大,这可能与硒化过程中锂-硒液相的形成有关.而且,锂可以进入铜锌锡硫硒晶格中,并在吸收层的表面积累,从而钝化缺陷,提升p-n结质量.因此,适量的锂掺杂可以提高器件的性能.此外,本工作探索了锂-钠共掺的影响.有趣的是,与Li-10%样品相比,钠元素的引入增强了吸收层拉曼光谱在328 cm^(-1)处硫的振动信号.10%锂钠共掺可将柔性Cu_(2)ZnSn(S,Se)_(4)薄膜太阳电池的效率进一步从6.62%提高到7.59%.本工作提供了一种基于刮涂法、简单有效的锂掺杂策略,并证明了锂-钠共掺存在相互作用机制.
