Emitter resistance definition Another factor that should be properly considered during the Solar cell design process is the emitter resistance. Emitter sheet resistance significantly contributes to the distributed series resistance of the solar cell. The series resistance (Rs) has an impact on the fill factor (FF) and in turn has an effect on the short circuit current …
