Abstract:
A solar cell testing system includes a multifunctional testing light source, a measuring unit, and an arithmetic unit. The multifunctional testing light source is configured to be switched to output a simulated solar light to a solar cell or asynchronously output a plurality of narrowband lights to the solar cell. The measuring unit is coupled to the solar cell and measures the solar cell's response to the simulated solar light and response to the asynchronously outputted narrowband lights. The arithmetic unit is coupled to the multifunctional testing light source and the measuring unit; it determines the solar cell's conversion efficiency and spectral response based on the solar cell's response to the simulated solar light and response to the asynchronously outputted narrowband lights.
