A critical milestone in solar cell fabrication will help pave the way for solar energy to directly compete with electricity generated by conventional energy sources.
Researchers improved the maximum voltage available from a cadmium telluride (CdTe) solar cell, overcoming a practical limit that has been pursued for six decades and is key to improving efficiency.
“It’s a significant milestone,” said Kelvin Lynn, Regents professor in WSU’s School of Mechanical and Materials Engineering and Department of Physics, who led WSU’s effort.
