WebAbstract. Alkali metal doping and grain boundaries (GB) have been at the center of attention within the Cu (In,Ga) (S,Se)2 photovoltaics community for years. This study provides the first experimental evidence that the GB of sodium-doped CuInSe2 thin films may undertake reversible oxidation even at room temperature, whereas undoped films may ... WebSolutions. ( 1) The heating curve shows how water changes from one state of matter to another based on temperature and the addition or removal of heat over time. Initially, ice is heated until its temperature reaches 0∘ and changes to liquid state. From the attached graph it is clear that until 100∘ the temperature will rise steadily.
