Abstract:

Machine learning techniques provide a breakthrough solution for the efficient development of perovskite light-emitting materials. This paper systematically reviews the innovative applications of this technology in material design, performance optimization, and experimental guidance, focusing on solving the bottlenecks of the inefficiency of the traditional trial-and-error method (320 experiments are required for the optimization of a single component of CsPbBr3, which takes 14 months) and the insufficient accuracy of theoretical calculations (the error in the prediction of the luminous efficiency of the Eu3+-doped system by DFT is as high as 40%). In terms of material structure and property prediction, cross-scale modeling based on neural networks has significantly improved the prediction accuracy of key parameters. The developed deep convolutional neural network (CNN) model analyzes crystal distortion through a 128×128×128 electron density grid, achieving a mean absolute error (MAE) of 0.08 eV for band gap prediction, with a prediction error of only 1.3% for CsPbBr3. The graph neural network (GNN) further quantifies the correlation between the stacking angle of layered perovskites and the band gap, with a prediction error of <0.05 eV. In material screening and optimization, the multi-objective algorithm achieves a synergistic improvement in performance indicators. The NSGA-II algorithm was used to screen Cs2SnGeI6, which achieved an external quantum efficiency (EQE) of 24% and extended the device lifetime (T??) to 1200 h. The Bayesian optimization framework combined with a robotic platform increased the photoluminescence quantum yield (PLQY) of CsPbBr3-xIx quantum dots from 45% to 89%, and the number of experimental iterations was reduced by 85%. In terms of experimental design, the microfluidic robotic platform screened the optimal ratio of CsPbBr1.5I1.5 within 24 h by dynamically adjusting the parameters (flow rate 10~100 μL/min, mixing time 110 s), with an emission wavelength error of ±3 nm and a PLQY of 92%. In the process optimization of flexible devices, the Bayesian algorithm increased the photoelectric conversion efficiency (PCE) from 18.2% to 21.5%, and the process time was shortened by 62.5%.
