RESEARCHERS with the Berkeley Lab have developed technology which could
enable low-cost, high efficiency solar cells to be made from virtually
any semiconductor material.
The work by the U.S. Department of Energy (DOE)'s Lawrence Berkeley
National Laboratory (Berkeley Lab) and the University of California (UC)
Berkeley opens the door to the use of plentiful, relatively inexpensive
semiconductors, such as metal oxides, sulfides and phosphides, for
These materials have been previously considered unsuitable for solar
cells because it is difficult to tailor their properties chemically.
This meant solar cells had to be made from relatively expensive
According to the researchers, they found the abundant materials can
instead be tailored for solar power applications by applying an electric
field, thus the name, screening-engineered field-effect photovoltaics"
