[19a-PB3-6] Improvement of solar cell characteristics by addition of ZnSe/ZnS:Mn/ZnS quantum dots as wavelength conversion materials
Keywords:wavelength conversion materials, solar cells, Mn doping
In recent years, the power generation efficiency of the solar cell have been improved by the addition of the wavelength conversion materials. We have developed the synthetic methods of ZnSe/ZnS:Mn/ZnS core/shell/shell nanoparticles. These nanoparticles have potential as a wavelength conversion material because ZnSe absorbs light in UV region and exhibits orange emission as a result of the d-d transition in the emission center of Mn2+. In this study, these nanoparticles were applied for photovoltaic cell. It was observed power generation major improvement.
