Have you ever imagined a paint that generate a electricity, a paint that will power our house hold appliances?.
Yes! the paint that work as a solar cell, generating electricity by using sunlight is going to come into action soon.
At University of Notre Dame in U.S.A., a team of researchers leaded by Professor Prashant Kamat has created this solar paint. The paint uses semiconducting nano particles to produce energy.
Professor Prashant Kamat said "By incorporating power-producing nanoparticles, called quantum dots, into a spreadable compound, we've made a one-coat solar paint that can be applied to any conductive surface without special equipment."
How It Is Made?
Titanium dioxide (nano sized particles) is coated with either cadmium selenide or cadmium sulphide, this particles are then suspended in a water-alcohol mixture to create a paste, this paste is nothing but the solar paint. The generated paste is then applied on a transparent conducting material, now if this material is exposed to light it literally generate electricity.
Advantages Over Traditional Solar Cells
1)Photovoltaic paint has a number of advantages over traditional solar cells such as, it doesn’t have the material limitations of silicon solar cells, so it theoretically provides many terawatts of electricity at a low cost.
2)The paint can absorb light across the visible spectrum, so even cloudy days will reap lots of energy.
3)It can be available in low cost then solar cell
Thus we know what electricity means to us now and in future, nowadays many of us use solar cell inorder to conserve our limited resources. Thus this solar paint has many advantages over solar cell and it can be a acceleration point in the field of conservation of resources, so let's hope for the best.
