标题： Transition Metal Dichalcogenide Solar Cells for Indoor Energy Harvesting

摘要： 随着物联网（IoT）的快速扩展，为在室内外运行的物联网设备提供高效且持久的能量收集器是必不可少的。 适用于室内光伏（PV）技术的有前途的材料包括过渡金属二硫属化物（TMDs），如MoS2、MoSe2、WS2和WSe2，这主要是由于它们具有高的吸收系数和自钝化表面。 在此，我们使用一种包含材料特定光学吸收以及辐射、俄歇和缺陷辅助肖克利-里德-霍尔复合的真实详细平衡模型，评估了单结TMD太阳能电池在各种室内照明条件下的性能。 我们发现，在500勒克斯下，TMD太阳能电池在荧光、LED、卤素和低光AM 1.5 G照明条件下，分别可以达到36.5%、35.6%、11.2%和27.6%的功率转换效率。 基于此，TMD太阳能电池在室内场景中可能优于商用光伏技术，表明它们在未来物联网能源解决方案中的可行性。 显示英文摘要

摘要： With the rapid expansion of the Internet of Things (IoT), efficient and durable energy harvesters for powering IoT devices operating indoors and outdoors are imperative. Promising materials for indoor photovoltaic (PV) technologies include transition metal dichalcogenides (TMDs) such as MoS2, MoSe2, WS2, and WSe2, mainly due to their high absorption coefficients and self-passivated surfaces. Here, we assess the performance of single-junction TMD solar cells under various indoor lighting conditions with a realistic detailed balance model including material-specific optical absorption, as well as radiative, Auger, and defect-assisted Shockley-Read-Hall recombination. We find TMD solar cells could achieve up to 36.5%, 35.6%, 11.2%, and 27.6% power conversion efficiency under fluorescent, LED, halogen, and low-light AM 1.5 G lighting, respectively, at 500 lux. Based on this, TMD solar cells could outperform commercial PV technologies in indoor scenarios, suggesting their viability for future IoT energy solutions.
