      abstract     = {Hydrogen produced by water electrolysis, and
                      electrochemical batteries are widely considered as primary
                      routes for the long- and short-term storage of photovoltaic
                      (PV) energy. At the same time fast power ramps and idle
                      periods in PV power generation may cause degradation of
                      water splitting electrochemical (EC) cells. Implementation
                      of batteries in PV-EC systems is a viable option for
                      smoothening out intermittence of PV power. Notably, the
                      spreading of PV energy over the diurnal cycle reduces power
                      of the EC cell and thus its overpotential loss. We study
                      these potential advantages theoretically and experimentally
                      for a simple parallel connected combination of PV, EC, and
                      battery cells (PV-EC-B) operated without power management
                      electronics. We show feasibility of the unaided operation of
                      PV-EC-B device in a relevant duty cycle and explore how
                      PV-EC-B system can operate at higher solar-to-hydrogen
                      efficiency than the equivalent reference PV-EC system
                      despite the losses caused by the battery.},
