“…2 Techniques have been developed to quantify the degree of coupling between junctions in a multi-junction solar cell, 3 and to model the effects using lumped-or distributedparameter models. 4 Letay et al have also modelled photon recycling effects in single junctions within a drift-diffusion simulator, using an iterative approach which involves running the simulator repeatedly with successive approximations of the coupled photocurrent. [5][6][7][8] Luminescent coupling has also been incorporated into simulations of light-emitting diodes.…”

Effects of luminescent coupling are observed in monolithic 5 V, five-junction GaAs phototransducers. Power conversion efficiency was measured at 61.6% 6 3% under the continuous, monochromatic illumination for which they were designed. Modeling shows that photon recycling can account for up to 350 mV of photovoltage in these devices. Drift-diffusion based simulations including a luminescent coupling term in the continuity equation show a broadening of the internal quantum efficiency curve which agrees well with experimental measurements. Luminescent coupling is shown to expand the spectral bandwidth of the phototransducer by a factor of at least 3.5 for devices with three or more junctions, even in cases where multiple absorption/emission events are required to transfer excess carriers into the limiting junction. We present a detailed description of the novel luminescent coupling modeling technique used to predict these performance enhancements. V C 2015 AIP Publishing LLC. [http://dx

Luminescent coupling in a top-limited multi-junction solar cell was investigated by employing a 3D circuit model and semiconductor physics. The calculation methods for computing both electro-luminescent and photo-luminescent coupling efficiencies were introduced. Since the calculation processes were circuit independent, they can be applied directly to any form of an equivalent circuit model of a solar cell. Moreover, an external approach to counteract the luminescent coupling effect was provided and the luminescent coupling process in a top-limited solar cell was illustrated. Finally, the bias and wavelength dependence of luminescent coupling efficiency was applied to the 3D circuit model and the simulation results were consistent with the measured data.
