The crystal anisotropy is of great importance to the charge carrier transport and optical absorption of perovskite materials. Owing to the discrepancy of tetragonal MAPbI3 crystal structure along with different directions, the optical and electronic properties are anisotropic, resulting in the different ...
Fast Growth of Thin MAPbI3 Crystal Wafers on Aqueous Solution Surface for Efficient Lateral‐Structure Perovskite Solar Cells 来自 国家科技图书文献中心 喜欢 0 阅读量: 113 作者:Y Liu,Q Dong,Y Fang,Y Lin,Y Deng,J Huang 摘要: Solar-grade single or multiple crystalline wafers are needed in ...
Figure 2a–d shows the crystal structure of the tetragonal MAPbI3 perovskite with (110), (002), (112) and (200) planes, respectively. Fig. 2e and f show thin film X-ray diffraction patterns of OPC and randomly oriented spherulitic MAPbI3 films, respectively; both show the tetragonal ...
The efficiency of perovskite solar cells has surged in the past few years, while the bandgaps of current perovskite materials for record efficiencies are much larger than the optimal value, which makes the efficiency far lower than the Shockley–Queisser efficiency limit. Here we show that utilizin...
Herein,we review the recent progress of single crystal perovskite X-ray detectors.First, we briefly introduced the basic concepts, detection mechanisms, figureof merits of perovskite X-ray detectors, and the preparation methods ofsingle crystal perovskites. Then, we summarized the significant ...
Using the CSFE representation (refer to section D of Supplemental Information for the features we used for representing elements), we achieve an MAE of 3.5 meV/atom for the perovskite total energies (Figure 3A) using EDNNs and an MAE of 0.069 ± 0.005 eV in 5-fold cross-validation for per...
Graph neural networks (GNNs) have been used previously for identifying new crystalline materials. However, geometric structure is not usually taken into consideration, or only partially. Here, we develop a geometric-information-enhanced crystal graph neu
Single-crystal CH3NH3PbI3 perovskite thin films with a tetragonal crystal structure are successfully fabricated by the GC-LCG process (Fig. 1d). The striking feature of this method is the ability to accurately control the crystal growth direction by taking advantage of the instant crystallization ...
