Hydrothermal Synthesis of $\hbox {Eu}^{3+}$ -Doped $\hbox {Y}(\hbox {OH})_{3}$ Nanotubes as D

Crisscrossed Eu³⁺-doped Y(OH)₃ nanotubes spin cast on the front surface of the screen-printed monocrystalline silicon solar cells (SPMSSCs) have been fabricated to enhance the conversion efficiency (CE) of the SPMSSCs. Organic-solvent-dispersible Eu³⁺-doped Y(OH)₃ nanotubes were hydrothermally synthesized according to the modified liquid-solid-solution synthetic strategy. Intense and well-resolved photoluminescent lines in the range of 525-700 nm are observed from the Eu³⁺-doped Y(OH)₃ nanotubes. The achievement of a CE improvement of more than 2% absolute from 15.2% to 17.2% in the SPMSSCs with Eu³⁺-doped Y(OH)₃ nanotubes was explored.
