TY - JOUR AU - Ho‐Baillie, Anita AB - The recent developments of photovoltaic (PV) have been transformed by the advent of metal halide perovskites. Their unique properties have not only pushed forward the efficiency of single‐junction solar cells but also opened new avenues for tandem solar cells. Tandem solar cells combine two or more solar cells with different bandgaps to maximize the conversion of a broad solar spectrum to electrical energy producing higher efficiencies than those of single‐junction solar cells. Perovskites, with tunable bandgaps, high efficiencies and ease of fabrication, have emerged as ideal candidates as both top and bottom subcells in a tandem, offering great promise. Perovskite‐based tandems involve the stacking or direct fabrication of a wide‐bandgap perovskite top absorber onto a silicon (Si), copper indium gallium selenide (CIGS), cadmium telluride (CdTe), the combination of low‐bandgap perovskite or an organic bottom absorber.As we stand on the cusp of a new horizon in solar energy conversion, this special section aims to provide an overview of recent advancements in perovskite‐based tandem solar cells disseminated in Solar RRL, highlighting some of the key findings from the scientific community. The contributions cover broad topics, including additive and composition engineering of perovskite subcells, large‐area fabrication, mechanical reliability, and interface passivation.
