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.&lt;/p&gt;&lt;p&gt;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 &lt;i&gt;Solar RRL&lt;/i&gt;, 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.
