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.
