Project Overview
Reflections from a photovoltaic (PV) cell present a significant source of efficiency loss in devices today. Maximizing efficiency requires that incident light is not reflected en route to the absorber layer and that the light that does enter is not subsequently reflected back out or transmitted through the device i.e asymmetric transmission is required. Metasurfaces provide a flexible design paradigm to enable the engineering of electromagnetic space and controlling the propagation of light and its interaction with matter through subwavelength structuring.
This project benefits the widespread adoption of solar technologies, by maximizing the economic efficiency of energy conversion through enhanced light matter interaction enabled by incorporation of metasurface layers that exhibit broadband asymmetric transmission within all traditional PV architectures. The project will produce a modeling platform for incorporation into all types of solar cells and device prototypes as deliverables.

Roadmap for phase change materials in photonics and beyondPhase Change Materials (PCMs) have demonstrated tremendous potential as a platform for achieving diverse functionalities in active and reconfigurable micro-nanophotonic devices across the electromagnetic spectrum, ranging from terahertz to visible frequencies. This comprehensive roadmap reviews the material and device aspects of PCMs, and their diverse applications in active and reconfigurable micro-nanophotonic devices across the electromagnetic spectrum. It discusses various device configurations and optimization techniques, including deep learning-based metasurface design. The integration of PCMs with Photonic Integrated Circuits and advanced electric-driven PCMs are explored. PCMs hold great promise for multifunctional device development, including applications in non-volatile memory, optical data storage, photonics, energy harvesting, biomedical technology, neuromorphic computing, thermal management, and flexible electronics.
