摘　　要：The photoelectric properties of In_(0.3)Ga_(0.7) As solar cells applied in laser wireless power transmission(LWPT) were studied when they were irradiated by 1070 nm continuous wave(CW) laser of various intensities. The influences of laser intensity on solar cell parameters extracted by the pollination algorithm were analyzed quantitatively.Results show that the conversion efficiency of the cell rose to the maximum and then decreased rapidly in the laser intensity range of 50–900 mW/cm2. With higher energy laser irradiation, the rise of ideality factor and reverse saturation current would lead to the degradation of voltage at the maximum power point, which was the main reason for the decrease of conversion efficiency. The results provide the basis for choosing the appropriate input energy in the case of different transmission systems.The photoelectric properties of In_(0.3)Ga_(0.7) As solar cells applied in laser wireless power transmission(LWPT) were studied when they were irradiated by 1070 nm continuous wave(CW) laser of various intensities.
