中文摘要
物联网设备的快速发展对适用于室内光照条件下为低功耗电子设备供电的可持续能源技术提出了迫切需求。在此背景下,室内光伏(IPV)技术成为实现物联网系统持续供能的重要解决方案。为提升室内光能转换效率,IPV吸光材料需具备1.7–1.9 eV的适宜带隙以匹配室内光源光谱,并具有高缺陷容忍性以抑制非辐射复合。全无机钙钛矿(AIPs),尤其是CsPbI3和CsPbI2Br,因其优异的光电性能和稳定性,成为理想的IPV材料。近年来,基于AIPs的IPV器件在室内光照下光电转换效率已突破40%,显著优于传统硅基太阳能电池。本文综述了AIP基IPV材料与器件的最新研究进展。
English Abstract
The rapid proliferation of Internet of Things (IoT) devices, ranging from smart sensors to wearable electronics, has intensified the demand for sustainable energy solutions capable of powering low-power electronics under indoor illumination. In this context, indoor photovoltaics (IPVs) emerge as a promising technology to enable continuous electricity supply for autonomous IoT systems. To maximize energy harvesting efficiency under indoor conditions, IPV absorbers require an optimal bandgap of 1.7–1.9 eV to match the spectral characteristics of indoor environments as well as high defect tolerance to minimize the defect-induced recombination. These requirements position all-inorganic perovskites (AIPs), particularly CsPbI3 and CsPbI2Br, as superior candidates for IPVs compared to conventional silicon absorbers. This review summarizes recent advancements on AIP-based IPVs, which lead to indoor efficiency exceeding 40%, far surpassing conventional silicon cells. This review also examines a
