Perovskites are of high potential in the ongoing academic research, due to their distinctive electrical properties and crystalline structures. Halide perovskites show high light emissive properties and panchromatic light absorption across the visible spectrum. The exceptional electrical characteristics, such as their long carrier lifespan, high diffusion length, and charge carrier mobility, allow the electric charges to be transported and collected effectively. Furthermore, by tuning the cations and anions composition, perovskite's opto-electrical properties can be altered. Moreover, dimension reduction affects their band gap and intrinsic features to induce higher structural stability but at the cost of the quantum confinement effect. Owing to their exceptional properties, halide perovskites are being researched in energy-related and semiconducting applications, hold high promise and the future looks bright. But challenges remain, and the larger question is what needs to be done to make them more stable.
由于其独特的电学性质和晶体结构，钙钛矿在当前的学术研究中具有很高的潜力。卤化物钙钛矿具有高光发射特性和全可见光谱范围内的光吸收能力。其卓越的电学特性，如长载流子寿命、高扩散长度和电荷载流子迁移率，使得电荷能够有效地传输和收集。此外，通过调整阳离子和阴离子的组成，可以改变钙钛矿的光电性质。而且，尺寸减小会影响其带隙和固有特性，从而诱导更高的结构稳定性，但代价是量子限制效应。由于其卓越的性能，卤化物钙钛矿正在能源相关和半导体应用领域进行研究，前景广阔，未来一片光明。但挑战依然存在，更大的问题是需要做些什么来使其更加稳定。
