A solar cell is made from semiconducting supplies, for example silicon, that were fabricated into a p–n junction. Utilizing much less active GaAs material by fabricating nanowires is another potential pathway to cost reduction.[ninety four] GaAs is a lot more normally used in multijunction photovoltaic cells for concentrated photovoltaics (CPV, https://holdennnlnk.bloginder.com/39022282/solar-cell-an-overview
