Effect of natrium sulphate concentration on indoor lights photovoltaic performance

One of the electron suppliers in a indoor lights photovoltaic system is the Na2SO4 electrolyte system. The aim of this research is to know the effect of sodium sulfate concentration on photovoltaic performance of indoor lights photovoltaic. The method used is liquid electrolyte system and gel electrolyte system made with various concentration on planar photovoltaic cell design using Cu2O/Al electrode plate. The ability of the Photoreactor is evaluated to obtain the characteristic curve of I-V at each Na2SO4 concentration. The average daily average power produced at concentrations of 0.25 M (gel), 0.5 M (gel), 0.75 M (solution), and 1 M (solution) were 14.218 μwatt, 6.688 μwatt, 38.334 μwatt, and 23.715 μwatt, respectively. The electrode plate used thin plate Cu2O/Al is 0.00246804 m2. The most optimum indoor lights planar photo-reactor is at a concentration of 0.75 M, with a daily average power performance for each square meter of 15.532 mWatt. Maximum power produced Photoreactor is achieved at a concentration of 1 M, ie 37.83245 mwatt/m2.
