TL;DR: In this paper, the recombination at the perimeter in the subcells that constitute a GaInP/GaAs/Ge lattice-matched triple-junction solar cell was investigated.

TL;DR: In this article, a temperature accelerated life test on commercial concentrator lattice-matched GaInP/GaInAs/Ge triple-junction solar cells has been carried out, where the acceleration of the aging has been accomplished by subjecting the solar cells at temperatures markedly higher than the nominal working temperature inside a concentrator, and the nominal photo current condition (820 X) has been emulated by injecting current in darkness.

TL;DR: In this article, the I-V curve is used to measure the electrical and optical coupling between subcells in a multijunction solar cell to determine the external quantum efficiency (EQE) measurement.

TL;DR: In this paper, the integration of ray-tracing methods for simulating the irradiance and spectrum maps produced by different optic systems throughout the solar cell surface, with a 3D fully distributed circuit model which simulates the electrical behavior of a state-of-the-art triple-junction solar cell under the different light distributions obtained with raytracing, is presented.

TL;DR: A prototype lightweight (1.5 kg/m) tile structure capable of photovoltaic solar power capture, conversion to radio frequency power, and transmission through antennas is demonstrated.
