Title:
GROUP 13 SELENIDE NANOPARTICLES
Document Type and Number:
Japanese Patent JP2018113453
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method of producing Group 13 selenide materials that can be used to produce photovoltaic devices with high efficiency at low cost.SOLUTION: A method of preparing Group 13 selenide nanoparticles comprises reacting a Group 13 ion precursor with a selenol compound. The nanoparticles have an MSesemiconductor core (where M is In or Ga) and an organic capping ligand attached to the core via a carbon-selenium bond. The selenol compound provides a source of selenium for incorporation into the semiconductor core and also provides the organic capping ligand. The nanoparticles are particularly suitable for solution-based methods of preparing semiconductor films.SELECTED DRAWING: Figure 2
