Perovskite light-emitting diodes (PeLEDs) have recently attracted great\nresearch luminescence at room temperature in interest for their narrow\nemissions and solution processability. Remarkable progress has been achieved\nPeLEDs in recent years. Here we present the new configuration of ambipolar\ntransparent perovskite light emitting device. The combination of voltage\ninduced p-i-n formation and ionically doped carbon electrodes and allows\nelectroluminescence in forward and reverse bias. Here we present easy-to-do\ntransparent ambipolar light emitting subpixel based on inorganic perovskite and\nsingle wall carbon nanotubes. For this experiment PeLEDs were assembled using a\nglass substrate with ITO stripes as bottom electrode; spin-coated\nCsPbBr3/I3:PEO composite as emissive layer; single wall carbon nanotubes\ndeposited by a simple press transfer process at room temperature. We\ndemonstrate a concept of stacked multicolor tandem pixel. Stack of transparent\nlight emitting units might allow fine color tuning in parallel tandem\nconnection without segregation compared to mixed halide perovskites. This\nconfiguration conforms pixel downsizing and make to fabrication of emissive\nmultijunction pixels in a stack.\n
