Finally, another noteworthy example is the use of junctions of varying dimensionality, such as a 3D/2D junction (Fig. 1d) in perovskite solar cells 14, leading to improvements in their efficiency and stability. Fig. 1: Schematic illustration of different types of heterojunction in photovoltaics and phase heterojunction fabrication procedure.
The simplest realization of a heterojunction is the combination of two different materials. For example, organic solar cells rely on the formation of a junction between donor and acceptor organic materials in a ‘bulk heterojunction’, thus facilitating charge separation at the heterointerface (Fig. 1a) 2, 6, 7, 8, 9.

Photocatalytic approaches in the visible region show promising potential in photocatalytic water splitting and water treatment to boost water purification efficiency.
However, in CdTe (ref. 11), CIGS (ref. 12) and GaAs (ref. 13) solar cells, a p–n junction can also be formed as a heterojunction (Fig. 1c).
