Environmental-friendly extraction of chlorophyll from pineapple plantation waste for dye sensitized solar cell (DSSC) fabrication

Improper disposal of pineapple waste can cause negative impact to the environment. To reduce the waste, we decide to recycle it. Recently, we discover that the present of chlorophyll in the pineapple plantation waste in the leaves can be used to fabricate the Dye Sensitized Solar Cell (DSSC) which is can be categorised as a renewable energy as well as environmental-friendly. The experimental and analysis was done to obtain the best condition of chlorophyll yield from the waste. The best condition from the mechanical extraction can be achieved by uncut the processed leaves at 3 cycle for extraction cycle by using the sugarcane machine. The highest value of chlorophyll a is 52.57 mg/ml and chlorophyll b is 113.05 mg/ml

Chlorophyll’s dependency towards electrical characteristics of banana midrib-based dye- sensitized solar cell for waste management solution

The application of Banana Midrib waste chlorophyll as an alternative natural dye in Dye Sensitized Solar Cell (DSSC) could be advantageous. The natural colors utilized in this study were derived from the chlorophyll of the banana midrib. TiO, chlorophyll and KI serve as a working electrode, photosensitizer, and electrolyte in the DSSC respectively. Chlorophyll, which can be extracted from majority of greenly plants, is one of the important substances in absorbing the light for energy harvesting. Since the concentration level of chlorophyll defers for each type, age or part of the plants, numerous studies related to these scopes have been actively performed. In this study, banana midrib that are mostly common waste will be benefited to extract different concentration levels of chlorophyll for the fabrication of DSSCs' purpose. The relationship between the chlorophyll’s concentration level and the output of electrical properties will be further analyzed
