solar battery backup for mobiles

We have to make an emergency call and have no battery left on cell....make use of the backup solar battery for few minutes.
Solar batteries or some battery that never need to be charged should be implemented into mobile phones. No more switch-off's due to low battery and no more re-charging hassles.
