A new technique developed by University of Toronto Engineering Professor Ted Sargent and his research group could lead to significantly more efficient solar cells.

In a paper published in the journal Nano Letters, the group describes a new technique to improve efficiency in what are called colloidal quantum dot photovoltaics. It’s a technology that already promises inexpensive and more efficient solar cell technology.
