Sunlight　is　an　abundant　and　clean　energy　source,　the　harvesting　of　which　could　make　a　significant　contribution　to　society＇s　increasing　energy　demands.　Metal　halide　perovskites　(MHP)　have　recently　received　attention　for　solar　fuel　generation　through　photocatalysis　and　solar-driven　electrocatalysis.　However,　MHP　photocatalysis　is　limited　by　low　solar　energy　conversion　efficiency,　poor　stability,　and　impractical　reaction　conditions.　Compared　to　photocatalysis,　MHP　solar-driven　electrocatalysis　not　only　exhibits　higher　solar　conversion　efficiency　but　also　is　more　stable　when　operating　under　practical　reaction　conditions.　In　this　Perspective,　we　outline　three　leading　types　of　MHP　solar-driven　electrocatalysis　device　technologies　now　in　the　research　spotlight,　namely,　(1)　photovoltaic-electrochemical　(PV-EC),　(2)　photovoltaic-photoelectrochemical　(PV-PEC),　and　(3)　photoelectrochemical　(PEC)　approaches　for　solar-to-fuel　reactions,　including　water-splitting　and　the　CO2　reduction　reaction.　In　addition,　we　compare　each　technology　to　show　their　relative　technical　advantages　and　limitations　and　highlight　promising　research　directions　for　the　rapidly　emerging　scientific　field　of　MHP-based　solar-driven　electrocatalysis.　©　2021　American　Chemical　Society.
