Discovery of an Efficient Solar Cell

January 11, 2013 | Leave a Comment

An international team of scientists working at Berkeley Lab’s Advanced Light Source (ALS), a premier source of X-ray and ultraviolet light beams for research, found that for highly efficient polymer/organic photovoltaic cells, size matters. Organic polymer-based photovoltaic cells are far less expensive to manufacture than silicon-based solar cells.  Scientists have long believed that the key […]
