The effect of external electric field on the performance of perovskite solar cells
2015 (English)In: Organic electronics, ISSN 1566-1199, Vol. 18, 107-112 p.Article in journal (Refereed) Published
Planar heterojunction perovskite solar cells were fabricated through a low temperature approach. We find that the device performance significantly depends on the external bias before and during measurements. By appropriate optimization of the bias conditions, we could achieve an 8-fold increase in the power conversion efficiency. The significant improvement in device performance might be caused by the ion motion in the perovskite under the external electric field.
