Abstract

We have designed and fabricated ultrathin (200nm) GaAs solar cells. Multi-resonant light trapping is achieved with a nanostructured TiO ₂ /Ag back mirror and the short-circuit current predicted by numerical calculations is Jsc= 25 mA/cm ² . We have investigated the physical origin of the resonances using analytical models that can be used to optimize the geometry of nanostructured mirrors suited for ultrathin solar cells. For the fabricated solar cell, the nanostructured TiO ₂ /Ag mirror is combined with localized ohmic contacts. The solar cells are patterned by Soft Nanoimprint Lithography and transferred on a glass substrate. A similar solar cell with Ag flat mirror was also fabricated. We have measured above 60% enhancement on short-circuit current compared to as-grown reference cell.
