Solar Energy Conversion using a Broad Band Coherent Concentrator with Antenna-Coupled Rectifiers

摘要

Through an internally funded research and development program, AMI Research and Development (AMI) has designed and developed a low profile, one-dimensional, solar coherent concentrator, intended for rectennas. A proof of concept prototype has been fabricated with an integrated photovoltaic array solar cell at the University of Illinois Urbana-Champaign (UIUC). Optical efficiency greater than 60% and an elevation field of view of 0.7 degrees has been modeled and confirmed with measurements. This device enables Antenna-Coupled Rectennas (ACR) to exceed one-sun solar performance efficiencies and provides a spectral splitting architecture to further enhance the efficiencies. We present the benefits of this device, prototype performance, and intended continued development of the ACRs.
