DSSCs primarily consist of ITO coated conductive glass, dye, electrolytes, photo anode and counter electrode. Natural dye is its main component for light absorption. This study utilized leaves that have chlorophyll and anthocyanin and considered pigments from sample (a) pineapple crown leaves, (b) Aratiles leaves and (c) purple potato leaves due to its abundance in the Philippines. This research aims to maximize the advantage of the DSSC on energy harvesting under direct sunlight and diffused light conditions. The 5x5 panels were tested and showed that the sample a have the highest terminal voltage ranging from 300-500 mV. While, those with dyes from sample b have 100-220 mV and sample c have 120-300 mV. The researchers then made a solar grid panel with 24 pieces arranged in 4 columns and 6 rows of 5x5 panels connected in series-parallel connection. The output voltage from sample a’s solar grid panel reached 3.05 V while the sample b and c leaves had 3.7 and 6.6 mV, respectively. In conclusion, pineapple crown leaves, that came from the waste materials, can be utilized to produce energy based on the experimentation results. The researchers encourage the future researchers to include low power load to measure the generated voltage of the DSSC.
