摘要

In the paper presented is a procedure for determining the optimal position of a triple-junction solar cell(TJ SC) on the Fresnel lens (FL) optical axis, at which the negative effect of the chromatic aberration (CA) on the performanceof TJ SC is weakened and the “FL-SC” system efficiency reaches maximum. The procedure based on the analysis ofdistributions of densities of the photocurrents generated by p-n junctions obtained from rated distributions of illuminationfluxes in the focal plane with allowing for the spectral response of separate junctions. The estimations are verified outdoors,and a good fit with natural experiment results was obtained. It was established that in the real system the efficiency maximumis achieved at the FF maximum, which allows using the dependence of the latter on the “FL-SC” distance as a probe forfunding the optimum SC position. It is also shown that, in optimizing the profile and parameters of Fresnel lenses for thesystems based on TJ SC with the purpose to weaken the chromatic aberration negative effect, the maximum of theconcentration in the focal plane could be used as a criterion.
