The concept of dual laser beam irradiation was firstly demonstrated on the photovoltaic cell, of which the temperature dependent efficiency was investigated for wireless power transmission. Then, an analytical model was established to calculate the multiple reflection absorption of any monochromatic light in multilayer structure, and the heat generation in photovoltaic cell was interpreted. Finally, the finite element analysis was used to simulate the temperature pattern of the photovoltaic cell subjected to laser irradiation. The spatial-temporal characteristic of the temperature field was obtained for improving the system in future.
