In one embodiment, a solar cell includes a transparent electrode, a photoactive layer, and an electron transport layer positioned between the transparent electrode and the photoactive layer, the electron transport layer being made of a piezoelectric material that is mechanically deformed such that it generates a voltage or charge that modifies an energy barrier between the electron transport layer and the photoactive layer.
