Abstract: Couple models are a standout amongst the most encouraging ideas towards prevalent power transformation efficiencies of natural sun based cells. An exact assurance of the power transformation productivity requires rectification of the otherworldly confuse and in this manner depends on precise outer quantum effectiveness (EQE) spectra. Because of the arrangement association of 2 sub cells in the pair design, the EQE of the couple sun powered cell repeats the EQE of one sub cell if a fitting inclination light is picked to specifically enlighten and henceforth forward predisposition the other sub cell. The subsequent inner voltage drop is then repaid by applying an outside voltage to the pair sunlight based cell. In this work, we use impedance spectroscopy to precisely foresee the base predisposition light force and the outer voltage to empower exact EQE estimations on both sub cells. We embody this method on natural couple sun oriented cells involving frightfully integral safeguards and recommend an all-inclusive convention for future estimations of the EQE.
