There are various applications of Solar energy harvesting in the field of Internet of Things (IoT).This paper will describe, analyze and review the key technologies in solar energy harvesting systems. Comparing the characteristics of several typical DC-DC converters, charge pump, especially, kinds of reconfigurable charge pump are designed to decrease the voltage gain discrete and extend conversion ratio matching for MPPT techniques. Besides, This paper also describe various MPPT techniques which shows evolution from 1-D MPPT to 3-D MPPT. Multi-batteries storing the unstable and discontinuous energy has been paid more attention in energy harvesting systems. Modelling solar cell by ANN technique is prospected in later research in the field of milliwatt solar energy harvesting.
