Commercialization is widely believed to be achievable for metal halide perovskite solar cells with high efficiency and low fabrication cost. However, stability remains a key obstacle for them to compete with established photovoltaic technologies. The photovoltaic community relies on the International Electrot...
It is interesting to note that there is obviously a prearrangement in groups of cations according to the later A (barium and strontium) and B (iron and zinc) sites in the perovskite on the nanometer scale. This finding was verified by the following characterization methods. First, we pr...
A "perovskite" is any material with the same crystal structure as the compound calcium titanium oxide, a semiconductor material like silicon. Perovskite solar cells use an artificial calcium titanium oxide-based material to create another type of thin-film solar panel. Like organic solar cells, per...
Environmental stability of perovskite solar cells (PSCs) has been improved by trial-and-error exploration of thin low-dimensional (LD) perovskite deposited on top of the perovskite absorber, called the capping layer. In this study, a machine-learnin
During liquid-solid CE, water is easily positively charged by solid surfaces29. Such a characteristic gives rise to the formerly pre- valent ion-transfer model, in which anions (hydroxide ions) dissolved in water continually migrate to the solid surfaces due to their high surface affinity, ...
In some flourishing fields, the true paradigm-shifting papers are far outnumbered by a mushrooming mass of more technical, incremental reports. However, the title is often sufficient to understand their entire content. See, for example, the field of lead halide perovskite photovoltaics. I will adm...
Stress-induced lattice distortions, that is, a tensile or compressive strain of the crystal structure, can significantly influence the physicochemical characteristics of materials by enhancing/inhibiting specific properties or by enabling new functionalities not allowed in the unperturbed structure. Strain eng...
