Along with the production and consumption of energy source, the indoor photovoltaics (IPV) gradually attracted public attention. As the power sources under low light conditions, IPV can satisfy the energy needs for some electron device with low power. This review focused and compared the characteristics of different types of IPV devices such as those based on silicon, dye, III-V semiconductors, organic compounds, and halide perovskites. Owing to optimal optical and physical properties, perovskite solar cells possess the potential to be IPV. Meanwhile, this review also concluded the limitations of IPV and gave the way to handle these key points such as power conversion efficiency (PCE)、toxicity and stability. Finally it expressed the prospects for IPVs
