CuGaSe 2半导体材料作为I-III-VI 2族的重要成员，因其优异的结构特性和在太阳能存储和转换方面的应用前景而引起了人们的极大关注。然而，由于CuGaSe 2的非层状晶体结构和多种反应前体的反应活性匹配，二维CuGaSe 2结构的可控制备仍然是一个艰巨的挑战，这将严重阻碍其性质和应用的深入研究。在此，非层状二维CuGaSe 2板具有高结晶度，均匀的尺寸和形态已首次合成了一个可行的阳离子交换策略。由于2D CuGaSe 2晶体的制备很少报道，因此特别强调了成分分析，结构表征和形成机制。此外，光吸收和光电性能测试结果表明，CuGaSe 2具有较高的光捕获能力和优异的光电性能。这项研究开辟了一个新的途径，为可行的非层状CuGaSe 2板具有高品质的晶体结构的制造，并提供了一个有前途的候选人，为开发新型太阳能转换和存储设备。首次采用阳离子交换法合成了具有高光捕获和优异光电性能的非层状二维CuGaSe 2材料。
CuGaSe2 semiconductor materials, as an important member of the I–III–VI2 family, have sparked tremendous attention due to their fascinating structure-related properties and promising applications in solar energy storage and conversion. Nevertheless, the controllable preparation of two-dimensional (2D) CuGaSe2 structures is still a daunting challenge owing to the intrinsic non-layered crystal structure and inaccessible reactivity-matching of multiple reaction precursors, which will seriously impede the much deeper research progress on their properties and applications. Herein, non-layered 2D CuGaSe2 plates possessing high crystallinity, and uniform size and morphology have been first synthesized by a feasible cation exchange strategy. Because the fabrication of 2D CuGaSe2 crystals is rarely reported, a particular highlight is laid on the compositional analysis, structural characterization, and formation mechanism. Furthermore, the optical absorption and optoelectronic measurements reveal that the as-synthesized CuGaSe2 plates exhibit high light harvesting capacity and excellent photoelectric performance. This study opens up a new avenue for the feasible fabrication of non-layered CuGaSe2 plates possessing a high-quality crystalline structure and provides a promising candidate for the development of novel solar energy conversion and storage devices. Non-layered two-dimensional CuGaSe2 materials with high light-harvesting and excellent optoelectronic properties have been first synthesized by a cation exchange strategy.
