Solar Cells – Visual Encyclopedia of Chemical Engineering

The same principles as other solar cells apply in that the energy absorbed in thin-film solar cells is converted to DC electricity, or AC electricity with the use of an inverter. Thin-film solar cells are often wired in series if multiple layers are desired for greater sunlight absorption, and then in parallel to maximize current, and thus the additive resulting voltage.
