In this paper, we show that strain gradients can greatly affect the total photovoltaic efficiency of perovskite solar cells. By adding the flexophotovoltaic effect on top of the standard photovoltaic effect of semiconductor junctions, the total output of perovskite photovoltaic devices can be either completely suppressed or greatly enhanced, depending on the relative sign of the strain gradient with respect to the semiconductor junction polarity.
