Professor Invents New Kind of Solar Cell

So far, chemist Pam Shapiro’s team has created a compound called a “quantum dot” that is made of elements that include copper, indium and selenium. Shapiro said that the quantum dots would be embedded between layers of a solar cell and would absorb energy that is otherwise wasted due to overheating. “These solar cells based on quantum dots aim to make better use of that excess energy,” Shapiro said.
