    Abstract

    The thermalisation of charge carriers in the UV-blue range, generated by the absorption of high-energy photons, is one of the major loss in silicon-based solar cells. The method investigated in this work for reducing these energy losses is via down-conversion (DC) layers doped rare earths ions placed on the front side of the silicon solar cells, allowing an efficient conversion from UV-blue photons to near-IR photons. This paper examines the Tb3+/Yb3+ energy transfer efficiency in a 70SiO2–30HfO2 glass-ceramics waveguides. The evaluation of the transfer efficiency between Tb3+ and Yb3+ is obtained by comparing the luminescence decay of Tb with and without Yb co-doping ions. A transfer efficiency of 25 % was obtained with the sample doped with a highest concentration of rare earth (5%).
