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

Boron nitride-incorporated NiOx as a hole transport material for high-performance p-i-n planar perovskite solar cells
TL;DR: The NiO:BN hole transport layer (HTLTL) has a deep energy level of highest occupied molecular orbital (HOMO) and smooth surface compared to pristine NiOx, which provide the better energy level alignment and better interface contact between NiO-BN HTL and perovskite, improving charge extraction and transportation and inhibiting recombination of charge as mentioned in this paper.
