BIO - SOLAR CELLS

Bio-Dyes are placed in third-generation sustainable energy materials for photovoltaic and proposed as alternatives to conventional dye-sensitized solar cells (DSSCs). New dye materials are also under extensive research due to the intrinsic properties of Ru(II)-based dyes and as a result to replace these rare and expensive Ru(II) complexes the cheaper and environmentally friendly natural dyes overcome as an alternative. Natural dyes provide low-cost and Eco-friendly DSSCs. There are various natural dyes containing anthocyanin chlorophyll flavonoid carotenoid etc. which have been used as sensitizers in DSSCs. The dye-sensitized nanocrystalline based Henna Beetroot Amla and Cactus pear fruit natural dyes sensitized solar cells has been proven to be a serious competitor to today widely used conventional solar cell. DSSCs have various advantages over silicon-based devices mostly natural dye solar cells have low materials cost simple fabrication abundance and acceptable performance as compared to other types of solar cells. With a lower thickness weight and possibility to use a dye with various colors or glass type DSSCs can be used for fashion architecture or design.
