The overarching goal of the CRC 1073 is to understand and control the elementary steps of energy conversion in materials with tunable excitations and interactions. Our studies focus on new materials systems and conversion routes that are highly promising for future applications in energy conversion and storage but are at an early stage of scientific discovery. Thus, the CRC is a knowledge-driven research initiative in the area of the physical and chemical sciences that contributes to the microscopic understanding of excitations, thermalization and conversion steps down to the atomic scale.In order to gain control of the elementary energy conversion steps, we work with materials systems, where excitation spectra and excitation interactions can be tuned by materials design or by active control. Three different types of elementary conversion steps are selected, along which we have aligned our projects in three topical areas (A,B,C) so that they form an entire conversion chain: Control of dissipation (A), conversion of optical excitations (B), and photon- and electron driven reactions (C). In the first CRC period, we demonstrated structural and active control tactics in different tuneable materials systems using a number of highly advanced atomic-resolution, ultrafast, spectroscopic and theoretical methods. In the second CRC period, we focused on the most promising systems, i.e. complex oxides, two-dimensional systems and molecular metal complexes, where we have achieved several exciting breakthroughs. In all three selected material systems, a large impact on pathways and efficiencies of energy conversion is found in tuning strongly correlated phases and highly correlated excitations.In the third SFB period starting in July 2021, we aim to develop the new paradigm of control of energy conversion by tunable correlations. To this end, the examples of control by correlations identified in the second period will be substantiated to create a coherent and predictive picture of energy conversion in material systems with strongly correlated excitations. This comprehensive understanding of the mechanisms will result in scientific guidelines for the development of novel technological applications and solutions.

CRC 1073的首要目标是理解和控制具有可调激发和相互作用的材料中能量转换的基本步骤。我们的研究重点是新材料系统和转换路线，这些系统和转换路线在能源转换和储存的未来应用中非常有前途，但仍处于科学发现的早期阶段。因此，CRC是物理和化学科学领域的一项知识驱动的研究计划，有助于微观理解激发，热化和转换步骤下降到原子尺度。为了获得基本能量转换步骤的控制，我们与材料系统合作，其中激发光谱和激发相互作用可以通过材料设计或主动控制来调整。选择了三种不同类型的基本转换步骤，沿着我们在三个主题领域（A，B，C）中对齐我们的项目，以便它们形成整个转换链：耗散控制（A），光激发转换（B），以及光子和电子驱动的反应（C）。在第一个CRC期间，我们使用许多高度先进的原子分辨率，超快，光谱和理论方法，在不同的可调材料系统中展示了结构和主动控制策略。在第二个CRC期间，我们专注于最有前途的系统，即复杂氧化物，二维系统和分子金属络合物，我们在其中取得了几项令人兴奋的突破。在所有三个选定的材料系统中，调谐强相关相位和高度相关激发对能量转换的途径和效率都有很大影响。在2021年7月开始的第三个SFB期间，我们的目标是通过可调相关性开发控制能量转换的新范式。为此，在第二阶段确定的相关性控制的例子将被证实，以创建一个连贯的和预测的图片，在材料系统的能量转换与强相关的激发。对这些机制的全面理解将为开发新的技术应用和解决方案提供科学指导。
