In two just-released studies, scientists have announced new ways of making solar cells less expensive and more efficient. In one of the projects, researchers from the University of Toronto demonstrated that nickel can work just as well as gold for electrical contacts in colloidal quantum dot solar cells. In the other, a team from California’s Lawrence Berkeley National Laboratory added selenium to zinc oxide, dramatically increasing the oxide’s efficiency in absorbing solar light. Both developments could result in more practical, affordable solar technology... Continue Reading Nickel and selenium could be used for cheaper, more efficient solar cells
