Using mercury nanotubes
india may be able to produce solar cells with a greater capacity to absorb solar energy. The secret behind this extra capacity lies in mercury compound nanotubes, scientists at iit Delhi have found out. Nanotubes, because of their structure, exhibit electrical and optical properties, which help in the absorption of solar energy and its conversion to electrical energy. Researchers have long dabbled with nanotube research to find an effective absorption material.
