摘要:

随着超快激光技术的不断发展,时间分辨光谱技术已成为研究太阳能转化与利用领域中超快时间尺度下微观光物理机制的重要工具。瞬态吸收光谱(Transient Absorption Spectroscopy, TAS)作为研究光诱导超快电子转移与载流子动力学过程的重要技术,具有揭示光生载流子产生、分离、传输及复合等关键动力学过程的独特优势。本文围绕光-化学能转换和光-电能转换,概述了TAS技术在光催化和太阳能电池两大主要太阳能转化与利用领域的应用。首先,根据光催化(侧重载流子迁移参与表面反应)与太阳能电池(强调载流子界面分离效率)对载流子的不同需求,分别从电子调控、空穴调控和表界面过程三个方面概括了促进载流子迁移利用的设计策略与研究进展。然后,特别关注了原位光谱在光-电-热等复杂应用条件下对能源转换微观过程及性能的影响机制。最后,总结了对太阳能转化与利用领域基础研究的前瞻性发展方向,为太阳能转化材料、反应、器件的理性设计与性能优化提供理论支持。

Abstract:

With the development of ultrafast laser technology, time-resolved spectroscopy has become an essential tool to study the microscopic photophysical mechanisms on ultrafast time scales in the field of solar energy conversion and utilization. Transient absorption spectroscopy (TAS), as an essential technology for studying photoinduced ultrafast electron transfer and photo-induced carrier dynamics, has the unique advantage of revealing key dynamic processes, such as the generation, separation, transport, and recombination of photogenerated carriers. Focusing on light-to-chemical and light-to-electrical energy conversion, this review summarizes TAS applications in two primary solar energy conversion systems: photocatalysis and solar cells. Firstly, according to the different requirements of photocatalysis (emphasizing migration for surface reactions) and solar cells (highlighting interfacial carrier separation efficiency), we summarize design strategies and recent advances for enhancing carrier utilization from three perspectives: electron manipulation, hole manipulation and surface interfacial processes. Subsequently, special attention is given to how in situ spectroscopy elucidates the influence mechanisms of microscopic energy conversion processes and device performance under complex application scenarios involving photo-electro-thermal couplings. Finally, the forward-looking development direction of basic research in solar energy conversion and utilization is summarized, which provides theoretical support for rational design and performance optimization of solar energy conversion materials, reactions, and devices.
