Use of Pigments Present in the Crude Aqueous Extract of the Spinach for the Simultaneous Solar Power and Storage at Natural Sun Intensity
The photogalvanic (PG) solar cell technique discussed in the present study has potential for both solar energy conversion and solar power storage at a time. The harvesting of the solar energy using costly, polluting, and synthetic dye sensitizers cannot be a sustainable method. Furthermore, the sens...
