• To evaluate the performance of a D-Xylose + Methylene Blue + Brij-35 + Sodium Lauryl Sulfate (NaLS) system under solar parameters.
• To compare the efficiency of mixed surfactants versus individual surfactants in PG cells for improved electrical output and energy storage.

Main Methods:

• Experimental investigation of photogalvanic cells under simulated solar conditions.
• Systematic study of various parameters influencing PG cell performance.
• Comparative analysis of PG cells utilizing mixed surfactants (NaLS + Brij-35) versus individual surfactants.

Main Results:

• The mixed surfactant system (D-Xylose + MB + Brij-35 + NaLS) demonstrated superior performance.
• Optimum results for the mixed system included open circuit voltage (921 mV), photopotential (698 mV), maximum photocurrent (311 uA), and short circuit current (245 uA).
• The mixed surfactant system achieved a higher fill factor (0.4521) and conversion efficiency (0.6769%) compared to individual surfactant systems.

Conclusions:

• Mixed surfactants, specifically NaLS + Brij-35, significantly enhance the efficiency of photogalvanic cells for solar energy conversion.
• The developed PG cell system with mixed surfactants is effective for improving electrical output and storing solar energy.
