Thin film solar cells made of amorphous or microcrystalline silicon provide renewable energy at the benefits of low material consumption. As a drawback, these materials don’t offer the high carrier mobilities of their crystalline counterpart. Due to low carrier mobilities, increased process times and material consumption, thick absorbing layers have to be avoided. For maintaining the absorption of the impinging light as high as possible, such thin film devices ask for photon management. Here we show how metallic nanoparticles that sustain the excitation of localized plasmon polaritons placed atop of the solar cell or in between two absorbing layers can increase the efficiency of solar cells. Numerical results for 1D as well as 2D periodic arrangements of nanoparticles will be shown.
