TL;DR: In this article, a cross-linked phenyl-C61-butyric acid methyl ester (PCBM) was used as an interlayer and (HC(NH2)2)0.66(CH3NH3) 0.34PbI2.85Br0.15 as the active layer to achieve small area devices and modules with a maximum steady-state power conversion efficiency of 18.1% and 14.9%, respectively.
Abstract: Commercially available phenyl-C61-butyric acid methyl ester (PCBM) is crosslinked with 1,6-diazidohexane (DAZH), resulting in films resistant to common solvents used in perovskite solar cell processing. By using crosslinked PCBM as an interlayer and (HC(NH2)2)0.66(CH3NH3)0.34PbI2.85Br0.15 as the active layer, we achieve small area devices and modules with a maximum steady-state power conversion efficiency of 18.1% and 14.9%, respectively.

TL;DR: In this paper, the authors showed that incorporating multi-walled carbon nanotubes (MWCNTs) in the bulk of the active layer of perovskite-based solar cells reduces charge recombination and increases the open circuit voltage.

TL;DR: In this article, a kind of Lewis-bases, urea(U), was used as a novel additive in synergy with DMSO to regulate the crystallization processes, which formed a smooth and large grain size perovskite film with no visible pinhole or crack found.

TL;DR: The results demonstrate that TPM-arylamines are a new class of HTMs for efficient and stable perovskite solar cells that can be prepared from relatively inexpensive raw materials with a facile synthetic route.
Abstract: A new class of hole-transporting materials (HTM) containing tetraphenylmethane (TPM) core have been developed. After thermal, charge carrier mobility, and contact angle tests, it was found that TPA-TPM (TPA: arylamine derivates side group) showed higher glass-transition temperature and larger water-contact angle than spiro-OMeTAD with comparable hole mobility. Photoluminescence and impedance spectroscopy studies indicate that TPA-TPM's hole-extraction ability is comparable to that of spiro-OMeTAD. SEM and AFM results suggest that TPA-TPM has a smooth surface. When TPA-TPM is used in mesoscopic perovskite solar cells, power conversion efficiency comparable to that of spiro-OMeTAD is achieved. Notably, the perovskite solar cells employing TPA-TPM show better long-term stability than that of spiro-OMeTAD. Moreover, TPA-TPM can be prepared from relatively inexpensive raw materials with a facile synthetic route. The results demonstrate that TPM-arylamines are a new class of HTMs for efficient and stable perovskite solar cells.
