Consequently, eliminating this hysteresis is a promising step toward ensuring the long-term performance of perovskite cells, and Bisquert expects that others working on perovskite solar cells will want to try Seok’s new recipe.

Efficiencies are often measured by plotting a curve of current against voltage—but for perovskites, the curves differ depending on whether the voltage is increasing or decreasing, an anomaly known as hysteresis that may have led to overestimates of perovskite performance in the past.

Indeed, the team speculate that the hysteresis curve is characteristic of the type of alcohol used to create the insulating layer.
