Methods to increase indium supplies for the manufacture of thin-film solar cells
Shortages of indium, a key metal found in thin-film solar cells, could limit their large-scale deployment in the future. A new study has outlined four ways that indium supplies could be increased to meet future demand. For example, indium could be extracted more efficiently from zinc ores, or historic wastes containing indium could be processed to extract the element. CIGS solar cells are a thin ...

Nanotechnology cuts costs and improves efficiency of photovoltaic cells
Researchers have summarised the most effective ways that nanostructures can improve the efficiency and lower costs of photovoltaic (PV) solar cells in a recent analysis. Sculpting ultra-thin solar cell surfaces at the nano-scale has been found to effectively boost their efficiency. Making solar cells ultra-thin reduces their material costs, but often at the expense of their efficiency. These ...
