Claim Text:
1. A method for simulating light, the method comprising: outputting a first light from a first filterer to a solar cell, wherein the first light output by the first filterer has a coarse spectrum that simulates the light in a selected environment, wherein the coarse spectrum is selected based on a standard which sets forth rules for testing the solar cell; and outputting a second light from a second filterer to the solar cell while the first light is output by the first filterer, wherein the second light output by the second filterer has a fine spectrum selected specifically for a group of junctions in the solar cell to test the group of junctions, wherein the second light output is configured to generate a current in the solar cell, and wherein outputting further comprises operating the first filterer and the second filterer such that the second light spectrum is about 10 percent to about 20 percent of a total light from both the first filterer and the second filterer that illuminates the solar cell.
