Considering global climate change concerns, issues related to the energy crisis and technologies reliant on non-fossil renewable energy sources are in high demand. Solar energy emerges as one of the alternatives among all renewable energy resources due to its economic viability and environmental sustainability. There are various types of solar photovoltaic (PV) technologies available for commercial applications, such as organic solar cells, silicon-based solar cells, dye-sensitized solar cells, and perovskite solar cells. Notably, one of the drawbacks of PV devices is their inability to generate power at night or during cloudy days (i.e., low-light conditions). One solution to this problem is to provide backup to the PV devices, such as batteries or energy storage packs. Another less explored alternative backup is the application of long persistent luminescence (LPL) materials as a secondary light source or down shifter. LPL materials can provide an afterglow that can last for hours which can be harvested by PV devices for power generation under low-light conditions. This short overview article discusses the fundamental mechanisms of LPL materials and the feasibility and challenges of integrating LPL materials into PV, which is hoped can provide useful insights for future research directions.
考虑到全球对气候变化的担忧，与能源危机以及依赖非化石可再生能源的技术相关的问题备受关注。太阳能因其经济可行性和环境可持续性，成为所有可再生能源中的替代能源之一。有多种类型的太阳能光伏（PV）技术可用于商业应用，如有机太阳能电池、硅基太阳能电池、染料敏化太阳能电池和钙钛矿太阳能电池。值得注意的是，光伏设备的一个缺点是它们无法在夜间或阴天（即低光照条件下）发电。解决这个问题的一种方法是为光伏设备提供备用电源，如电池或储能组件。另一种较少被探索的备用方案是应用长余辉发光（LPL）材料作为辅助光源或降频器。LPL材料可以提供持续数小时的余辉，光伏设备可以利用这些余辉在低光照条件下发电。这篇简短的综述文章讨论了LPL材料的基本机制以及将LPL材料集成到光伏中的可行性和挑战，希望能为未来的研究方向提供有用的见解。
