孙涛-张怀研究团队采用机器学习势方法，对CaPv的波速进行了深入研究。机器学习势方法保持了第一性原理的精度，同时大大提高了模拟效率和规模，从而得以观察到前人未能发现的新现象。研究表明，在通常地幔温压条件下，CaPv的波速与地幔PREM模型十分接近，难以通过地震学观测识别。 但在对应冷俯冲板片在下地幔底部的温压条件，CaPv将处于四方-立方相转变的边缘，此时立方相CaPv会显示出强烈的前驱软化 ...

Researchers at Nanjing Tech University in China have designed a perovskite solar cell that uses a Mortise-Tenon (M-T) structure to create a large-contact area between the perovskite absorber and ...

To prepare the PSCs, two perovskite precursor solutions were used: 1.67-eV (Cs 0.05 FA 0.80 MA 0.15 Pb(I 0.75 Br 0.25) 3) and 1.53-eV (Cs 0.05 FA 0.9 MA 0.05 PbI 3 + 5 % MAPbCl 3).

To anyone who has spent some time in photovoltaic (PV) power circles, the word ‘perovskite’ probably sounds familiar. Offering arguably better bandgap properties than traditional silicon cells ...
