University of Michigan Achieves a 44% Power Conversion Efficiency

Thermophotovoltaic cells have been developed by our partners at the University of Michigan, these cells achieve a significantly improved power conversion efficiency of 44% at 1435°C. This has allowed them to convert heat into electricity by capturing infrared photons, making them ideal for use in heat batteries. Heat batteries store excess renewable energy as thermal energy, which can later be converted back into electricity using these cells. The new design features an “air bridge” structure, which traps photons that can be converted to electricity and recycles those that can’t, further enhancing efficiency. This innovation moves thermophotovoltaic technology closer to practical grid use, offering a cost-effective and versatile alternative to traditional battery storage, with the potential to reach even higher efficiencies in the future.

Having arrived in Brazil, our partner’s logistics team takes the lead, taking it out of the wooden box so that it can fit through the door of the facility. The journey resulted in the standard small bumps and dents that are categorized and logged so that our installation team can quickly and effectively get the system up and running, which they do.

Finally, all that’s left to do is to fabricate some superconducting circuits, and further the field of quantum computing. Our partners at Centro Brasileiro de Pesquisas Fisicas (CBPF) expressed their excitement at having gained the capabilities  of partnering with us in this translated LinkedIn post:

 

It is with great enthusiasm that we announce the arrival of the newest equipment, from Angstrom Engineering, to the Quantum Technologies Laboratory of CBPF. This laboratory is complementary to Labnano, one of the strategic laboratories of SisNANO – the National System of Nanotechnology Laboratories of the Ministry of Science, Technology and Innovation (MCTI).

SisNANO is comprised of a set of laboratories focused on research, development and innovation (RD&I) in nanosciences and nanotechnologies, with the essential characteristic of being multi-user and open access to public and private institutions.

Acquired with funding from Finep and support from MCTI, the new equipment will allow CBPF to advance in the manufacture of superconducting quantum nanodevices, such as Josephson junctions and SQUIDS. These devices are essential for the development of future quantum chips, which promise to transform areas such as computing, secure communication and metrology.

The impact of this advance is also connected to related projects funded by FAPERJ, CNPq and Petrobras, consolidating a robust research ecosystem in Brazil.

This achievement reinforces the commitment of CBPF and MCTI to leading the frontier of scientific research, contributing to enabling the country to compete in a global scenario marked by disruptive and strategic advances.

We would like to thank the institutions involved and the professionals who made this achievement possible. We invite the scientific, technological and industrial community to closely monitor the transformative results that this new infrastructure will provide.
