An award-winning Indo-Canadian theoretical physicist Sajeev John has developed a process wherein sunlight can be trapped and confined in ultrathin and flexible silicon sheets, offering a far higher efficiency in generating electricity than conventional solar power technology.Applications based on the research conducted by University of Toronto professor of physics Sajeev John are currently in progress.In an interview with the Hindustan Times, Prof John, who was born in Thiruvalla in Kerala, said his design is based on “the invention of photonic crystals”, the novel materials that can trap and guide light on a microscopic scale. Certain photonic crystal architectures can be very effective in capturing sunlight and making it bounce around for a prolonged time in a thin material. As a result, the light can be absorbed almost completely in a flexible film of silicon only one-tenth…
