Abstract
A method and apparatus for testing photovoltaic solar cells using multiple flashlamps is disclosed. The method comprises steps of providing a plurality of flashlamps, pulsing the flashlamps to expose the solar cell to light for a short period of time, preferably less than about 100 milliseconds, and measuring a characteristic of the photovoltaic solar cell in response to the radiation emitted by the flashlamps. In a preferred embodiment of the invention, for use in testing triple junction solar cells, the apparatus includes six flashlamps: one flashlamp tailored to emit light in a portion of the light spectrum for stimulating each of the three junctions, and three additional flashlamps for conducting specialized testing.
