Up-Conversion in Er3+-Doped Ge25Ga5Sb5S65 Chalcogenide Glass for Enhancement of Silicon Solar Cell Efficiency

Er<sup>3+</sup>-doped Ge<sub>25</sub>Ga<sub>5</sub>Sb<sub>5</sub>S<sub>65</sub> chalcogenide glass was studied as a potential material for up-conversion application to enhancement of silicon solar cell efficiency. Thermal properties were studied via DSC measurement, optical properties via variable angle spectroscopic ellipsometry and photoluminescence… CONTINUE READING
