Metal halide perovskite solar cells (PSCs) remain one of the most discussed and researched materials in the world due to their promising materials characteristics and performance metrics. PSCs possess qualities that find applications in civilian and military sectors. PSCs have been demonstrated to have power conversion efficiencies (PCE) of over 24%, 30% reduction in deposition costs, direct band gap with tunability ranging from 1.1-1.8 eV, and the ability for synthesis at room temperature. This correspondence seeks to shed light on the current Department of Defense (DoD) efforts in PSCs, as well as demonstrate reduction in cost, environmental impact, and CO2 footprint. Successes in stabilization of the materials and challenges to be overcome for perovskites are discussed. This work shows the possibility of integrating perovskite materials with existing mature solar panel technologies for successful marketization of perovskites and diversification of applications. Furthermore, this work demonstrates the opportunities that are presented by perovskite materials to the DoD community and unique challenges that are overcome with the application of this technology.
An objective performance of the reflective-band imaging systems is required in order to provide the warfighter with the right technology for a specific task. Various methods to measure and model performance in the visible (Vis) spectral regions have been proposed in the literature. This correspondence shows the influence of the spectral region averaging on the monochromatic modulation transfer function (MTF). This works unequivocally shows that the illumination source plays a crucial role in the accurate predictive analysis of the system performance. For accurate analysis the illumination sources need to be carefully considered for the atmospheric conditions. This work shows the possibility of using an LED configuration in the system performance analysis. Such configurations need rigorous calibration in order to become a valuable asset in system characterization.
