Abstract

Abstract : Floatstone‐like TiO2 microparticles with an efficiently enhanced Mie scattering effect were developed by thermofusing of rutile‐type TiO2 submicron particles on the template core of poly(acrylate) microspheres. The light reflectance of the floatstone‐like TiO2 microparticles was approximately 10% higher than that of the usual rutile‐type TiO2 submicron particles in a wavelength range from 400 to 850 nm. The diffuse reflectance of the microparticles is enhanced by the formation of a floatstone‐like structure, whereas there is no difference in the specular reflectance of the particles. As an application of the floatstone‐like TiO2 microparticles, the contribution of the particles to the light‐trapping effect of a solar cell was examined. The power conversion efficiency of the solar cell was enhanced by 22% with the introduction of a light‐scattering layer composed of the floatstone‐like TiO2 microparticles.
