Fig. 1. (a) Schematic diagram of In0.3Ga0.7As solar cell. (b) The picture of the solar cell.

Fig. 2. I–V curves of the solar cell under different laser power densities. (The dots are experimental results, and the lines are calculation results. The unit of Plaser is mW/cm2.)

Fig. 3. Effects of Plaser on the current at short circuit and maximum power point. (The function in the figure is a linear fitting function of the short circuit current.)

Fig. 4. Effects of Plaser on the voltage at open circuit and maximum power point. The inset shows the relationship between Voc/Vm and Plaser.

Fig. 5. Effects of Plaser on fill factor and conversion efficiency.

Fig. 6. Effects of Plaser on series and parallel resistances.

Fig. 7. Effects of Plaser on the ideality factor and reverse saturation current.

Fig. 8. Effects of Plaser on the photo-generated current (the function in the graph is a linear fitting expression)
