Peak Algal electrical outputs primarily occurred at the stationary phases of Algae development. In addition, the peak stationary absorption for Chlorella Vulgaris was 123 (A), Nannochloropsis 286 (A), and 142 (A) for Spirulina. Nannochloropsis presented the highest electrical output of 35 mW. Chlorella resulted in 30.2 mW, whereas Spirulina resulted in 31 mW. However, Spirulina experienced the most drastic increases in electrical outputs when approaching the stationary
