Aluminum Black
if aluminum formed black oxides on its outer layer can it be used as a photovoltaic cell?
recently i found out that when a copper sheet is heated, black oxides form on its faces. this enables it to "capture" light or act as photovoltaic cell when submerged in salt water or any electric conductive surrounding. so in this case if an aluminum sheet also forms black oxides on its outer layer can it also be used as a photovoltaic cell like copper?
Aluminum oxide is not black and is very good electrical insulator, hence may not be good for photovoltaic cell.
