Above: A novel approach to a long-standing materials science challenge has birthed a record-breaking monocrystalline cadmium telluride solar cell, which shatters an efficiency record and boasts the highest voltage ever for its type of cell. Researchers led by electrical engineering Professor Yong-Hang Zhang and Assistant Professor Zachary Holman published the results of their collaboration in the journal Nature Energy.
