Photovoltaics supply a growing share of power to the electric grid worldwide. To mitigate resource intermittency issues, these systems are increasingly being paired with electrochemical energy storage devices, e.g., Li-ion batteries, for which ensuring long and safe operation is critical.
The scientific approach would be to properly match voltage and current between PV module and battery. For maximum overall efficiency, the integrated PV-battery cell needs to be operated at maximum power point of the PV cell.
The overall efficiency of an integrated PV-battery system is a product of photoelectric conversion efficiency of PV and energy storage efficiency of the battery. The maximum overall efficiency is the photoelectric conversion efficiency of PV.
