Here we report a systematic study of all-inorganic perovskite-inspired systems based on CsₓPbI₂Brₓ alloys with x ranging from 0.95 to 4. The identified optimal non-stoichiometric composition Cs₁.₂PbI₂Br₁.₂ delivered the best optoelectronic, structural and photovoltaic characteristics in combination...
