Argonne-Northwestern Solar Energy Research Center

Argonne-Northwestern Solar Energy Research Center is a premier Energy Frontier Research Center (EFRC) established by the United States Department of Energy in 2009. It is a collaborative partnership between Northwestern University and Argonne National Laboratory, dedicated to fundamental scientific research aimed at dramatically improving the efficiency and lowering the cost of solar energy conversion and storage. The center brings together a multidisciplinary team of scientists and engineers to address critical challenges in photovoltaics and solar fuels.

Overview

The center was founded as part of a major initiative by the Office of Basic Energy Sciences within the DOE Office of Science to accelerate scientific breakthroughs in renewable energy. Led by Director Michael R. Wasielewski of Northwestern University, ANSER integrates world-class expertise in chemistry, materials science, physics, and engineering from its partner institutions. Its research is primarily conducted at facilities on the campuses of Northwestern University in Evanston, Illinois and Argonne National Laboratory in Lemont, Illinois. The collaborative model is designed to bridge fundamental discovery at the university with the advanced characterization and scale-up capabilities of a national laboratory.

Research Focus

The scientific mission is organized around understanding and controlling energy and charge transfer processes at the nanoscale in organic and hybrid materials. A core focus is developing new materials for third-generation photovoltaics, including organic solar cells, perovskite solar cells, and quantum dot-based technologies. Parallel research thrusts investigate artificial photosynthesis for producing solar fuels such as hydrogen from water splitting. Key interdisciplinary challenges include engineering molecular assemblies, controlling exciton dynamics, and designing interfaces between light-absorbing materials and catalysts to minimize energy losses.

Key Facilities and Capabilities

Researchers leverage an exceptional suite of national user facilities and institutional resources. This includes unparalleled access to the Advanced Photon Source and the Center for Nanoscale Materials at Argonne National Laboratory. These facilities enable advanced techniques such as ultrafast X-ray spectroscopy, scanning probe microscopy, and electron microscopy to probe materials in real time. At Northwestern University, the NUANCE Center provides state-of-the-art nanofabrication and characterization tools. The Integrated Molecular Structure Education and Research Center offers comprehensive spectroscopy and diffraction resources critical for synthesizing and analyzing new compounds.

Major Scientific Contributions

The center has produced seminal advances in the understanding of singlet fission, a process that could enable solar cells to exceed the Shockley–Queisser limit. Work on perovskite photovoltaics has led to improved stability and insights into ion migration within these materials. In solar fuels research, teams have developed innovative molecular catalysts for oxygen evolution reaction and carbon dioxide reduction with high efficiency. Notable publications have appeared in journals like Science, Nature, and the Journal of the American Chemical Society, significantly influencing the global photochemistry and energy materials communities.

Organizational Structure and Partnerships

The center operates under the executive leadership of Director Michael R. Wasielewski and includes principal investigators from both Northwestern University and Argonne National Laboratory. It maintains strong collaborative ties with other Energy Frontier Research Centers, such as the Center for Molecular Electrocatalysis and the Light-Material Interactions in Energy Conversion center. Beyond the DOE, partnerships extend to industry through the Solar Energy Technologies Office and to international research institutions. The center also plays a vital role in training the next generation of scientists through its graduate fellowship and postdoctoral researcher programs.
