State-of-the-art, high-performance solar cells and light-emitting diodes normally rely on tedious layer-by-layer sequential deposition of carrier transport layer and light-absorbing/emitting layers, which is not cost-effective. Several recent exciting works have demonstrated surprising breakthroughs in terms of simplified processing of these optoelectronic devices. Upon the incorporation of carbazole phosphonic acid molecules and their derivatives into precursor ink beforehand, charge-selective contact could spontaneously self-assemble at the buried interface between the conducting substrate and photoactive layer, which results in the construction of simplified-structured devices that yield comparable optoelectronic performances to the conventionally fabricated devices with full architectures. Herein, the recent groundbreaking advancement of high-performance optoelectronic devices fabricated via a convenient codeposition technique is summarized, with particular emphasis on elucidating the chemical mechanism of self-assembly mode and highlighting the unique advantages of this strategy on crystallization regulation, targeted defect passivation, carrier dynamics modulation, and comprehensive device performance improvement. Finally, the associated challenges are critically discussed and the future research directions are insightfully proposed, which can revolutionize the pathway toward constructing highly efficient optoelectronic devices in a cost-effective manner and setting forward to future commercialization.

高性能太阳能电池和发光二极管的自组装分子辅助简化加工
最先进的高性能太阳能电池和发光二极管通常依赖于繁琐的逐层顺序沉积载流子传输层和光吸收/发射层，这是不经济的。最近的几项令人兴奋的工作在简化这些光电器件的加工方面展示了令人惊讶的突破。将咔唑膦酸分子及其衍生物预先掺入前体墨水中后，电荷选择性接触可以在导电基底和光活性层之间的掩埋界面处自发自组装，从而构建结构简化的器件，其产生可比的性能。光电性能优于传统制造的具有完整架构的器件。本文总结了近年来通过便捷的共沉积技术制备高性能光电器件的突破性进展，特别强调了自组装模式的化学机制，并强调了该策略在结晶调控、靶向缺陷钝化、载波动态调制，以及器件综合性能提升。最后，对相关挑战进行了批判性讨论，并深刻地提出了未来的研究方向，这可以彻底改变以成本效益的方式构建高效光电器件的途径，并为未来的商业化做好准备。
