All the colours of the sun

Usually, solar simulators use a Xenon arc lamp followed by a series of filters and lenses to obtain a spectrum roughly similar to that of the sun as well as an even distribution and intensity. With recent developments in technology, light emitting diodes (LEDs) become promising alternatives to these arrangements. Each LED in an array can be controlled separately, so you should be able to simulate the standard AM1.5 solar spectrum closer than in the classical arrangement. Alternatively, with the proper control, you are theoretically able to produce any spectral distribution you want – so not even the sky is the limit here. Your project will expand and improve on previous work.
