With plasmonic photovoltaics in mind, electrostatic localized surface plasmon eigenresonances of metallic tin (β‐Sn) nanoparticles buried in crystalline silicon (c‐Si) are analyzed using a Green's function surface integral eigenvalue equation method. We show that by shaping the particles, plasmon resonances can be achieved at wavelengths where c‐Si is a poor light absorber. This might be important for plasmon assisted Si solar cells.
