North Carolina State University use a food additive to make an efficient, semi-printed plastic solar cell. Better yet the new solar cells can be created without the use of environmentally hazardous halogen solvents and can be manufactured at room temperature, which has strong implications for large-scale commercial production. Plastic solar cells, or organic photovoltaics, are […]

Columbia scientists have demonstrated it is possible to manufacture solar cells that are far more efficient than existing silicon photovoltaic cells. Its a discovery that could have profound implications for future energy economics. The team, led by Xiaoyang Zhu, a professor of Chemistry at Columbia University, focused its efforts on a new class of solar […]
