According to the University of Turku scientists, low-cost, lightweight and flexible dyes can be utilized to trap the sunlight, instead of using fragile and expensive crystalline silicon-based semiconductor solar panels.
Jongyun Moon and his Arho Suominen and Aulis Tuominen explained in the International Journal of Technology, Policy and Management about the dye-sensitized solar cells (DSCs), which are considered to be a universal energy resource with no costly and complex clean-room manufacturing methods when compared to present solar panels. Rapid research on novel solar energy conversion technology may possibly create an industrial revolution in generating electricity that can be accessible by everyone without government or other financial support.
Major sections of the globe have not adopted solar energy, due to the lack of financial incentives and government subsidies. Solar energy for domestic use can possibly minimize the dependability on grid power systems, as a part of a sustainable way towards electricity production. It offers a localized grid for use in distant locations, mainly in sunny climes. Sunlight when struck on a white pigment titanium dioxide layer of DSC, the absorbed solar power sucks electrons from dye molecules in a layer that is present below this coating, and as a result the flow of electrons generates current.
Moon and his colleagues have recommended that DSCs can replace the silicon technology, as the manufacturing of DSCs is cheaper and simpler. More development work is needed for the current DSCs, whose efficiency is less when compared to silicon devices.
