A new three-layer inverted structure of organometal halide perovskite light-emitting diodes was introduced and studied. An Electron Transport Layer of Polyethylenimine was introduced to improve surface morphology and facilitate carrier injection. Photoluminescence (PL) and electro-luminescence (EL) could be observed on aluminum foil and pure silver cathode substrate. While the luminescence of over 25 cdm2 could be measured on devices on aluminum foil, better stability across devices fabricated on silver substrates still needs improvement.
