The concept of a multijunction solar cell is already widely used in thin-film silicon solar cell technology. In the multijunction solar cell structure, two or more solar cells are stacked on top of each other.

Tandem solar cells are the next step in the photovoltaic (PV) evolution due to their higher power conversion efficiency (PCE) potential than currently dominating, but inherently limited, single-junction solar cells.
Apart from all-perovskite tandems, there are also some reports on monolithic tandem solar cells combining perovskite and organic solar cells with however moderate efficiencies around 10%. [162, 163] Also, 2T-multijunction devices without recombination layer were introduced, which do not require sub-cell current matching.
There are four main categories of photovoltaic cells: conventional mono- and poly- crystalline silicon (c-Si) cells, thin film solar cells (a-Si, CIGS and CdTe), and multi-junction (MJ) solar cells.
Traditional photovoltaic cells are commonly composed of doped silicon with metallic contacts deposited on the top and bottom. The doping is normally applied to a thin layer on the top of the cell, producing a p–n junction with a particular bandgap energy, Eg.
Potentially, a different HTL, such as SAM or ALD deposited NiO could be used, possibly resulting in high PCEs also in flexible tandem devices. The results above show that perovskite/CIGS tandem solar cells also have great potential for different applications.
