物联网 (IoT) 为日常物体和环境提供“智能”和数据连接，以提高生活质量和各种人类活动的效率。然而，物联网设备生态系统的持续指数增长（迄今为止已达到数百亿台）对如何为此类设备供电提出了挑战。本进度报告讨论了能量收集如何应对这一挑战。然后，考虑到室内光伏 (IPV) 的可部署性、可靠性和功率密度，它如何成为一种有吸引力的能量收集解决方案。对于 IPV 来说，要提供一种为物联网设备供电的环保途径，其基础材料和制造工艺必须低毒且在产品生命周期内不会对环境造成危害，这一点至关重要。讨论了迄今为止开发的一系列 IPV 技术（包括现有技术和新兴技术），重点是其环境可持续性。最后，对基于新兴无铅钙钛矿吸收体的 IPV 进行了研究，强调了它们在低成本、持久且高效的能量收集方面的地位和前景，且对最终用户和环境无害。通过研究环保型 IPV 的新兴途径，及时洞察 IPV 的有前途的方向，从而可持续地推动物联网革命。
The Internet of Things (IoT) provides everyday objects and environments with "intelligence" and data connectivity to improve quality of life and the efficiency of a wide range of human activities. However, the ongoing exponential growth of the IoT device ecosystem-up to tens of billions of units to date-poses a challenge regarding how to power such devices. This Progress Report discusses how energy harvesting can address this challenge. It then discusses how indoor photovoltaics (IPV) constitutes an attractive energy harvesting solution, given its deployability, reliability, and power density. For IPV to provide an eco-friendly route to powering IoT devices, it is crucial that its underlying materials and fabrication processes are low-toxicity and not harmful to the environment over the product life cycle. A range of IPV technologies-both incumbent and emerging-developed to date is discussed, with an emphasis on their environmental sustainability. Finally, IPV based on emerging lead-free perovskite-inspired absorbers are examined, highlighting their status and prospects for low-cost, durable, and efficient energy harvesting that is not harmful to the end user and environment. By examining emerging avenues for eco-friendly IPV, timely insight is provided into promising directions toward IPV that can sustainably power the IoT revolution.
