High-throughput robot-assisted experimentation is applied for the optimization of the synthesis conditions, targeting the highest yields of Cs2AgBi(Sb)I6 perovskites (ca. 90 mass%) with the lowest bandgap (1.78 eV). We provide new insights into the pathways, mechanisms, and dynamics of the formation of iodide double perovskites, reporting stable lead-free double iodide perovskites crystallized in a non-conventional tetragonal symmetry. 001052820 536__ $$0G:(DE-HGF)POF4-1212$$a1212 - Materials and Interfaces (POF4-121)$$cPOF4-121$$fPOF IV$$x0 001052820 588__ $$aDataset connected to DataCite 001052820 650_7 $$2Other$$aThin-Films and New Concepts 001052820 650_7 $$2Other$$aPerovskites 001052820 7001_ $$0P:(DE-Juel1)188483$$aRaievska, Oleksandra$$b1$$ufzj 001052820 7001_ $$aKinge, Sachin$$b2 001052820 7001_ $$0P:(DE-Juel1)177626$$aHauch, Jens$$b3$$ufzj 001052820 7001_ $$0P:(DE-Juel1)176427$$aBrabec, Christoph$$b4$$ufzj 001052820 773__ $$a10.4229/EUPVSEC2025/2DO.8.3 001052820 909CO $$ooai:juser.fz-juelich.de:1052820$$pVDB 001052820 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)178670$$aForschungszentrum Jülich$$b0$$kFZJ 001052820 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)188483$$aForschungszentrum Jülich$$b1$$kFZJ 001052820 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)177626$$aForschungszentrum Jülich$$b3$$kFZJ 001052820 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)176427$$aForschungszentrum Jülich$$b4$$kFZJ 001052820 9131_ $$0G:(DE-HGF)POF4-121$$1G:(DE-HGF)POF4-120$$2G:(DE-HGF)POF4-100$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-1212$$aDE-HGF$$bForschungsbereich Energie$$lMaterialien und Technologien für die Energiewende (MTET)$$vPhotovoltaik und Windenergie$$x0 001052820 920__ $$lyes 001052820 9201_ $$0I:(DE-Juel1)IET-2-20140314$$kIET-2$$lHelmholtz-Institut Erlangen-Nürnberg Erneuerbare Energien$$x0 001052820 980__ $$acontrib 001052820 980__ $$aVDB 001052820 980__ $$aI:(DE-Juel1)IET-2-20140314 001052820 980__ $$aUNRESTRICTED
