Paper Abstract

In the paper the influence of luminescent layer made of tellurite glass doped with Yb3+/Er3+ on parameters of silicon photovoltaic cell in the near infrared region was investigated. Luminescence properties of the fabricated glass under 976 nm excitation were measured. As a result of the conducted works enhancement of conversion efficiency of NIR radiation utilizing upconversion process in tellurite glass doped with RE was obtained. Parameters of PV cell with active layer: open circuit voltage increase of 5,5% for sample codoped with Yb3+/Er3+ system and 2,7% for sample doped with Er3+, 100% is the signal from pure PV cell illuminated by 976 nm laser.
