제목 Eco-Friendly Dye-Sensitized Solar Cells Based on Water-Electrolytes and Chlorophyll
초록 Dye-sensitized solar cells (DSSCs) are high efficiency, low cost, and easy fabrication renewable energy devices. Many DSSCs are using organic solvent electrolytes, which are toxic and explosion hazard, and expensive ruthenium dye such as N3 and N719. Here, we made eco-friendly DSSC by replacing organic electrolyte to water-based electrolyte. Also, organic synthetic dyes can be replaced by chlorophyll extracted from spinach. The effect of aging time after the device fabrication and the electrolyte composition on the photovoltaic performance of the eco-friendly DSSCs were investigated. Plasma treatment of TiO2 was adopted to improve the dye adsorption as well as the wettability of the water-based electrolytes on TiO2. Making DSSCs, using aqueous electrolyte and chlorophyll, can make more eco-friendly energy devices.
