Tandem　solar　cells　(TSCs)　comprising　stacked　narrow-bandgap　and　wide-bandgap　subcells　are　regarded　as　the　most　promising　approach　to　break　the　Shockley–Queisser　limit　of　single-junction　solar　cells.　As　the　game-changer　in　the　photovoltaic　community,　organic–inorganic　hybrid　perovskites　became　the　front-runner　candidate　for　mating　with　other　efficient　photovoltaic　technologies　in　the　tandem　configuration　for　higher　power　conversion　efficiency,　by　virtue　of　their　tunable　and　complementary　bandgaps,　excellent　photoelectric　properties,　and　solution　processability.　In　this　review,　a　perspective　that　critically　dilates　the　progress　of　perovskite　material　selection　and　device　design　for　perovskite-based　TSCs,　including　perovskite/silicon,　perovskite/copper　indium　gallium　selenide,　perovskite/perovskite,　perovskite/CdTe,　and　perovskite/GaAs　are　presented.　Besides,　all-inorganic　perovskite　CsPbI3　with　high　thermal　stability　is　proposed　as　the　top　subcell　in　TSCs　due　to　its　suitable　bandgap　of　≈1.73　eV　and　rapidly　increasing　efficiency.　To　minimize　the　optical　and　electrical　losses　for　high-efficiency　TSCs,　the　optimization　of　transparent　electrodes,　recombination　layers,　and　the　current-matching　principles　are　highlighted.　Through　big　data　analysis,　wide-bandgap　perovskite　solar　cells　with　high　open-circuit　voltage　(Voc)　are　in　dire　need　in　further　study.　In　the　end,　opportunities　and　challenges　to　realize　the　commercialization　of　TSCs,　including　long-term　stability,　area　upscaling,　and　mitigation　of　toxicity,　are　also　envisioned.　©　2020　WILEY-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim
