Abstract
An illustrative solar cell may include an electron conductor, an absorber, a hole conductor, and one or more other layers that help reduce interfacial charge recombination within the solar cell for improved solar cell efficiency. In one example, an electron inhibiting/hole transporting layer is provided that blocks or at least substantially inhibits movement of electrons that may otherwise move from within the absorber and/or electron conductor into the hole conductor of the solar cell, while permitting holes to travel from the absorber to the hole conductor. In some cases, the electron inhibiting/hole transporting layer may be transparent or substantially transparent to incident light so that the incident light may reach the absorber material.
