  • Patent number: 9941837
    Abstract: A process for determining a nonlinear response of a photovoltaic cell that includes: producing a first set of first light pulses including a first light that includes a first photon flux; and different first magnitudes of first photon flux; producing a second set of second light pulses that include: a second light including a second photon flux; and different second magnitudes of second photon flux; repeating the first light pulses in a selected combination with the second light pulses to produce a combinatorial set of combinatorial light pulses including: a combinatorial light comprising a combinatorial photon flux and different combinatorial magnitudes; irradiating a photovoltaic cell separately with the first set, second set, and the combinatorial set; separately producing, a first, second, and combinatorial photovoltaic output; and solving a system of linear equations to determine the nonlinear relationship between the photovoltaic output and the magnitude of flux.
