ABSTRACT:
A hearing aid employs a permanent built-in rechargeable storage cell or battery, and a solar cell or other photo cell which powers the electronics of the hearing aid and recharges the storage cell. Favorably, a thin film amorphous silicon cell is employed, and is affixed onto an outward-facing surface of the aid. The photocell is connected in parallel with the storage cell and is of sufficient power capacity to power the amplifier and recharge the storage cell under average ambient light conditions. The storage cell is favorably of sufficient capacity to power the amplifier for at least several hours under darkness conditions.
