Assessing the Environmental Impact of Pnictogen‐based Perovskite‐Inspired Materials for Indoor Photovoltaics

Advanced Energy Materials, Volume 15, Issue 5, February 4, 2025.
Pnictogen‐based perovskite‐inspired materials are a potential sustainable technology for indoor photovoltaics and completely lead‐free. Environmental sustainability is analyzed for four Sb‐ and Bi‐ perovskite‐inspired solar cells. Although still in its early stages, the environmental impacts and energy payback time are lower compared with current ...

Ion Replacement Electrorefining

ECS Proceedings Volumes, 1994
We are developing a two-step electrochemical process for purifying and separating metals called ion replacement electrorefining. In each step, metal cations formed by oxidation at an electrode replace other metal cations that are reduced at another elecmae.

Mass Transfer Modeling of CsCl During Crystallization of Molten LiCl‐KCl‐CsCl Salt Mixture

Chemical Engineering &Technology, Volume 47, Issue 8, Page 1061-1070, August 2024.
Crystallization is a passive separation technique, and parametric modeling has been done to arrive at an optimal crystallizer design to separate impurities from a ternary molten salt mixture. Abstract Metallic alloy fuels from fast reactors will be reprocessed by a non‐aqueous electrochemical technique known as electrorefining. Electrorefining of spent

Material availability assessment using system dynamics: The case of tellurium

Progress in Photovoltaics: Research and Applications, Volume 32, Issue 4, Page 253-266, April 2024.
System dynamics is used to assess the availability of tellurium for CdTe PV. Results show that increasing the CdTe PV manufacturing capacity is insufficient if tellurium is unavailable. Expanding existing Te‐rich ores does not alleviate tellurium scarcity while improving tellurium yield from copper electrorefining is a more efficient mitigation ...

Effect of Green Additives in Copper Electrorefining Bath: Current Efficiency and Surface Characterization Investigation

Journal of Chemistry, Volume 2024, Issue 1, 2024.
The copper electrorefining performance in acidified copper sulfate solution utilizing the potential‐dynamic polarization technique was established. This was inspected through measurement and comparison of limiting current‐cathode potential relationship in a solution of regularly rising methanolic extract concentrations (from 50 to 1000 ppm) of Lablab ...
