摘要：

The efficiency of a solar cell can be increased by using photon management to make better use of the solar spectrum. In particular the downconversion process which permits us to obtain two low-energy ( 980 nm) photons from one high-energy photon. In particular we present a system consisting of a 70 SiO2-30 HfO2 glass ceramic waveguide co-doped with Tb3+ and Yb3+ ions. We present the assesment of the energy transfer efficiency from an excited Tb3+ ion to two Yb3+ ions in its vicinity.
