Abstract
(EN)
A perovskite optoelectronic device, comprising: a substrate (1), an electrode layer and a functional layer, wherein the electrode layer is disposed on a surface of the substrate, the functional layer is disposed between the electrode layers; the functional layer at least comprises a perovskite layer, wherein the perovskite layer is a perovskite material having a structure of self-assembled multi-quantum wells; by means of adjusting the composition of the material, controllable adjustment of the widths of the multi-quantum wells and effective energy transfer between the multi-quantum wells are made possible; a laminating color may be ultraviolet light, visible light and near infrared light. Thus, the issue wherein a thin film made of an existing perovskite material is discontinuous and unstable can be effectively solved. The perovskite optoelectronic device is simple in process, low-cost and suitable for wide applications in large-scale, low-cost industrial production of flexible substrates and high-performance devices. Also disclosed is a perovskite material that can be used in photoluminescent, electroluminescent, photovoltaic and thin-film transistor devices.

L'invention concerne un dispositif optoélectronique pérovskite, comprenant : un substrat (1), des couches d'électrode et une couche fonctionnelle, la couche d'électrode étant disposée sur une surface du substrat, la couche fonctionnelle étant disposée entre les couches d'électrode ; la couche fonctionnelle comprend au moins une couche de pérovskite, la couche de pérovskite étant un matériau pérovskite ayant une structure de puits quantiques multiples auto-assemblés ; au moyen d'un réglage de la composition du matériau, un réglage réglable de la largeur des puits quantiques multiples et du transfert d'énergie effectif entre les puits quantiques multiples sont rendus possibles ; une couleur de lumière peut être une lumière ultraviolette, une lumière visible et une lumière infrarouge proche. Le problème de discontinuité et d'instabilité d'une couche mince d'un matériau pérovskite existant peut ainsi être efficacement résolu. Le dispositif optoélectronique pérovskite est simple à mettre en œuvre, peu coûteux et approprié pour une large application dans la fabrication industrielle à grande échelle et à bas coût de substrats souples et de dispositifs à hautes performances. L'invention concerne également un matériau pérovskite qui peut être utilisé dans des dispositifs photoluminescents, électroluminescents, photovoltaïques et des transistors à couches minces.
