摘要 目前,钙钛矿太阳能电池最常使用的钙钛矿材料为CH_3NH_3PbI_3,其禁带宽度为1.55eV,导致低于该能量值的太阳光的光子无法被直接地吸收利用。因此,提高器件对太阳光谱的响应范围是提高钙钛矿太阳能电池性能的关键。稀土上转换材料可以将低能量近红外光转换为高能量可见光,所以,稀土上转换发光的应用是提高钙钛矿太阳能电池性能的较为可行的途径。本文概述了稀土上转换发光的基本机制,介绍了钙钛矿太阳能电池的结构和工作原理,综述了该太阳能电池的研究现状及其主要优势,重点阐述了稀土上转换发光在钙钛矿太阳能电池中的应用,最后对该太阳能电池的发展前景进行了展望。 Due to many outstanding properties, perovskite solar cell (PSC) has attracted more and more attention from scientists. At present, CH3NHaPbI3 is the most commonly used for perovskite materials, and its energy gap is 1.55eV. The solar photons below 1.55eV of energy cannot be absorbed directly. Therefore, increasing the response of the PSC for the solar spectrum is the key to improve the performance of solar cells. Because low-energy photons can translate into a high-energy photon by using rare earth up-conversion luminescence materials, applying rare earth up-conversion luminescence is an efficient path to improve the performance of PSCs. In this paper, fundamental mechanisms of rare earth up-conversion luminescence, structure and working principle of the PSC are summarized, respectively. According to the related literatures, the research status is mainly introduced. Finally, the prospects on PSC are discussed.
