Here it is a Post about my original Technological & Scientific field of Study and Training: Photonics and Optoelectronics. One of most exciting applications in these fields concerns Solar Photovoltaic Cells, its role in Renewable Energy Solutions being crucial. This Video is from Sajeev John, a University Professor at the University of Toronto Canada:
His groundbreaking work in the field of light localization that enables light to be controlled at the microscopic level has earned him an international reputation. He is a pioneering theoretician in photonic band gap (PBG) materials. This new class of optical materials presents exciting possibilities in the fields of physics, chemistry, engineering and medicine. PBG materials could eventually be used for optical communications/information processing, clinical medicine, lighting and solar energy harvesting.
