Tandem solar cells can either be individual cells or connected in series. Series onnected cells are simpler to fabricate but the current is the same though each cell so this contrains the band gaps that can be used. The most common arrangement for tandem cells is to grow them monolithically so that all the cells are grown as layers on the on substrate and tunnel junctions connect the individual cells.
