Cuprous oxide dye-sensitized solar cells (DSSCs) were fabricated through the use of chlorophyll from malunggay leaves (Moringa oleifera) as sensitizers. UVVisible spectroscopy results indicated the presence of chlorophyll in malunggay leaves. Four set-ups, each with replicates, were made: one with no pigment and three with cuprous oxide submerged in the pigment for 24, 48, and 72 hours, respectively. The measured voltage outputs of the DSSCs show that as the time of submersion of the cuprous oxide on the pigment increases, the voltage output produced also increases. In terms of efficiency testing, it was found that the solar cells with chlorophyll-soaked cuprous oxide had a lower efficiency than those with cuprous oxide not soaked in chlorophyll pigment.
