Powering seawater desalination plants with photovoltaics
A German research team has investigated the feasibility of a large-scale PV-powered seawater reverse osmosis desalination plant in Jordan and has found that keeping the concentrate flow constant is the most appropriate desalination operating mode.
The impact of impurity concentrations in gallium-doped p-type silicon ingots
The University of Konstanz and Chinese panel maker Longi have assessed the impact of gettering on LeTID in industrial Czochralski grown gallium-doped p-type silicon ingots and have found that defect density depends on impurity concentrations in the melt, which are observed in the case of interstitial iron concentrations.
