Abstract：The improved performance of InP/InGaAsP/InP multiple quantum well waveguide solar cells by light scattering from deposited dielectric or metal nanoparticles are reported. The integration of metal or dielectric nanoparticles above the quantum wells solar cells device is shown to couple normally incident light into lateral optical propagation paths, with optical confinement provided by the refractive index contrast between the quantum well layers and surrounding material. With optimization, short-circuit current density increases of 12.9% and 7.3% and power conversion efficiency increases of 17% and 1% are observed for silica and Au nanoparticles, respectively.
