Abstract
Semiconductor nanowire (NW) solar cells have promising potentials in solar energy conversion, benefiting from their low fabrication cost and enhanced optical absorption through light confinement. Recently, we have shown that the absorption efficiency can be significantly improved in lead sulfide (PbS) NWs with high refractive indices, by a direct observation of 350% external quantum efficiency (EQE). In this proceeding paper, we further examine the optical resonance mechanism in this promising nanomaterial. Particularly, we will present our recent results on resonance modes calculation, polarization and substrate effects on optical resonance, and intensity dependent minority carrier diffusion lengths in single PbS NW Schottky junction solar cells.
