TLDR
A series of metal acetylacetonates produced by a full low-temperature (below 100 °C) process are successfully employed to obtain both "multistable" and high-performance planar-inverted perovskite solar cells.Abstract:
A series of metal acetylacetonates produced by a full low-temperature (below 100 °C) process are successfully employed to obtain both "multistable" and high-performance planar-inverted perovskite solar cells. All the three kinds of champion cells in small area exhibit over 18% in conversion-efficiency with negligible hysteresis, along with a conversion efficiency above 16% for planar PSCs in an aperture area of over 1 cm2 .read more

TL;DR: It is found that varied PSC responses are attributable to two causes, capacitive effect associated with electrode polarization provides a slow transient non-steady-state photocurrent that modifies the J-V response, and modification of interfacial barriers induced by ion migration can modulate charge-collection efficiency so that it causes a pseudo-steaden state photocurrent.
