Write a detailed note on bucky-ball.

I. Bucky balls are composed of carbon atoms linked to three other carbon atoms by covalent bonds.

II. The carbon atoms are connected in the same pattern of hexagons and pentagons you find on a soccer ball.

III. The most common bucky-ball contains 60 carbon atoms and is sometimes called C₆₀.Other sizes of bucky balls range from those containing 20 carbon atoms to those containing more than 100 carbon atoms.

IV. The covalent bond between carbon atoms make bucky balls very strong, and the carbon atoms readily form covalent bonds with a variety of other atoms.

V. Bucky balls are used in composites to strengthen material.

VI. Bucky balls are very good electron acceptors. They accept loose electrons from other materials.

VII. It increases the efficiency of solar cells in transforming sunlight into electricity due to its property of good electron acceptor.
