    Abstract: The invention employs a group of LED devices as a light source for emitting light with different wavelengths towards the solar cell under test. A set of test signal data composed of mutually orthogonal test signals are used to power the LED devices to emit light. The solar cell, upon receiving light from the LED devices powered by the test signal data, generates detected values which are in turn converted into electric signals. A processor device is then used to separate component signals contributed by the respective LED devices from the signals and compare the component signals to the output power level corresponding to the test signal data and/or to the optical energy levels radiated from the respective LED devices, thereby obtaining the spectral response of the solar cell to the different wavelengths of light.
