Xiaotian Zhang, an undergraduate student in materials science and engineering, removed a sample of silicon diselenide from an annealing furnace. The researchers are investigating the use of semiconductor crystalline silicon diselenide (SiSe2) as a thin film to sit atop a more conventional silicon solar cell. They are exploring how best to synthesize the material into a thin film as well as how to treat or “dope” it with other elements to improve its photovoltaic qualities.
