Hydrothermal Synthesis of Eu3+-Doped Y(OH)3 Nanotubes as Downconversion Materials for Efficiency Enhancement of Screen-Printed Monocrystalline Silicon Solar Cells

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.
