Monolithic III-V triple-junction solar cells under different temperatures and spectra

This paper concentrates on the performance of lattice-matched and metamorphic triple junction solar cells under different temperatures and spectral conditions. This information is essential for a better understanding of concentrator photovoltaic systems. It is well known that, compared to single-junction cells, the performance of multi-junction solar cells shows a stronger dependence on the incident spectrum. The influence of temperature can in first approximation be described with linear coefficients, that themselves do no depend on the incident spectrum, which will be shown in the paper.
