Abstract

This paper reports progress in the development of a miniature photovoltaic (PV) arrays consisting of monolithically series connected AlGaAs/GaAs PV cells used in combination with polymeric photoluminescent fibers to recharge batteries of unattended ground sensors (UGS). Outdoor tests of the arrays showed feasibility of this approach. Optimization of the fibers design (material used, diameter, coupling, etc.) is discussed. Better optical matching of the fibers and PV cells was achieved through replacing of GaAs photoactive layers by AlGaAs ones having a higher bandgap.
