The concept of the Internet of Things (IoT) is a future development opportunity for mankind, which is a system that realize the interaction of various electronic devices through wireless communication. With the rise and development of this concept, the energy demand gap of self-powered equipment in IoT has emerged. The construction of an off-grid power system will make the wireless network of IoT easy to integrate and meet the higher requirements of power supply equipment in terms of size, weight, energy-consumption, and cost. Indoor photovoltaics (IPVs) can provide stable and long-term power guarantee by collecting indoor light, which are perfectly matched with IoT. Photovoltaic cells based on a-silicon, dye, organic compounds, and halide perovskite have been proved to be suitable for IPVs. Among them, perovskite indoor photovoltaics (PIPVs) have attracted much attention due to its advantages of tunable bandgap, high output voltage, flexible preparation, and low cost. In addition, the indoor stability and toxicity of PIPVs are also discussed in this Perspective.
