His scientific research has been recognized by, among others, two State Natural Science Awards. He is currently an editorial board member of several international journals including ChemNanoMat (VCH-Wiley), Sustainable Energy (Hans Publishers), International Journal of Nanotechnology (Inderscience Enterprises Ltd.), etc.

报告摘要：

多尺度材料的装配和集成对新一代太阳能器件的运行至关重要，需要基础科学的设计和阐述。关键是要了解和利用定制材料的内在特性，以及材料组件之间的相互作用，从而实现所需要的功能。我将介绍我们在通过溶液过程连接和组装各种纳米结构方面的最新成果。这些新型材料已经被用做高效太阳能转换装置的高效光吸收层，载流子传输层，界面层和表面反应促进剂，特别是在钙钛矿太阳能电池和光电化学电池中。并将讨论这些结果对新太阳能装置的未来发展的影响。

Abstract:

Materials assembly and integration at multiple length scales are critical to the functioning of new generation solar energy devices, and call for basic science informed design and elaboration. The key is to understand and leverage the intrinsic properties of the tailored materials as well as the interplay between the material components so as to realize the desired functions. In this contribution, I will present some of our recent results in interfacing and assembling various nanostructures by solution processes. The novel materials have been explored as efficient light absorbers, carrier transporters, interlayers and surface reaction promoters for high-performance solar energy conversion devices, particularly perovskite solar cells and photoelectrochemical cells. Implications of these results on the future development of new solar energy devices will be discussed.
