探索用于能源生产和储存的有前景的材料是本世纪最大的挑战之一。太阳能是最重要的可再生能源之一，由于其广泛的可用性和低环境影响。金属卤化物钙钛矿已经成为一类具有独特性质的半导体材料，包括可调带隙、高吸收系数、宽吸收光谱、高电荷载流子迁移率和长电荷扩散长度，这使得能够实现广泛的光伏和光电应用。自从钙钛矿太阳能电池的第一个实施例显示出3.8%的功率转换效率以来，设备性能在几年内已经提高到了22.1%。在这方面，我们讨论了通过各种沉积过程产生的不同形式的钙钛矿材料。我们专注于其与能源相关的应用，并讨论当前的挑战和可能的解决方案，旨在刺激潜在的新应用。
Exploring prospective materials for energy production and storage is one of the biggest challenges of this century. Solar energy is one of the most important renewable energy resources, due to its wide availability and low environmental impact. Metal halide perovskites have emerged as a class of semiconductor materials with unique properties, including tunable bandgap, high absorption coefficient, broad absorption spectrum, high charge carrier mobility and long charge diffusion lengths, which enable a broad range of photovoltaic and optoelectronic applications. Since the first embodiment of perovskite solar cells showing a power conversion efficiency of 3.8%, the device performance has been boosted up to a certified 22.1% within a few years. In this Perspective, we discuss differing forms of perovskite materials produced via various deposition procedures. We focus on their energy-related applications and discuss current challenges and possible solutions, with the aim of stimulating potential new applications.
