“…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

The luminescent coupling effect in practical multi-junction solar cell is spatially in-homogeneous even under uniform irradiation and temperature distribution. The spacial inhomogeneity of luminescent coupling is modeled and simulated under various scenarios. Quasi three-dimensional equivalent model of tandem solar cell is extended to adapt to temperature-dependent luminescent coupling. Vertical current of each region of the cell is dominated by temperature or irradiation. In addition, the luminescent coupling current of each subcell pair is mainly regulated by the surface voltage profile of the cell. Front grids, busbars, and lateral resistance have a great impact on the luminescent coupling current. Non-uniform irradiation only affects the shape of contour lines, but the overall trend of luminescent coupling current profile remains unchanged. Moreover, when temperature distribution variance is large, some areas of the photovoltaic cell will reverse bias and convert to a load, which leads to a rather irregular distribution of luminescent coupling current.
