Journal ArticleDOI
Optimization of solar powered hydrogen production using photovoltaic electrolysis devices
Thomas L. Gibson,Nelson A. Kelly +1 more
TL;DR: In this article, the efficiency of the PV-electrolysis system was optimized by matching the voltage and maximum power output of the photovoltaics to the operating voltage of proton exchange membrane (PEM) electrolyzers.
Journal ArticleDOI
Improved photovoltaic energy output for cloudy conditions with a solar tracking system
Nelson A. Kelly,Thomas L. Gibson +1 more
TL;DR: In this article, the authors describe measurements of the solar irradiance made during cloudy periods in order to improve the amount of solar energy captured during such periods, and show that tilting a solar module or sensor away from the zenith reduces the irradiance relative to a horizontal configuration, and thus receives the highest amount of this isotropically-distributed sky radiation.
Journal ArticleDOI
Solar photovoltaic charging of lithium-ion batteries
Thomas L. Gibson,Nelson A. Kelly +1 more
TL;DR: In this paper, the authors used high efficiency crystalline and amorphous silicon PV modules to recharge lithium-ion battery modules, achieving a system efficiency of nearly 15% and battery charging efficiency of approximately 100%.
Journal ArticleDOI
Nitric acid and ammonia in urban and rural locations
TL;DR: In this paper, the average ammonia and nitric acid concentrations over all sites were 1.7 ppb and 0.7 pb, respectively, and seasonal data collected in Warren, Michigan showed ammonia concentrations were lowest in the winter.
Journal ArticleDOI
Design and characterization of a robust photoelectrochemical device to generate hydrogen using solar water splitting
Nelson A. Kelly,Thomas L. Gibson +1 more
TL;DR: In this article, the authors described the results of experiments to determine an optimal configuration for an efficient and durable a-Si-based photoelectrode for use in PEC devices.
