TL;DR: The rationalization of the photovoltaic performances exhibited by different configuration devices discussed in this paper can provide new and unexpected prospects for engineering the interface between the active layer of perovskite-based solar cells and the hole transporters.
Abstract: Due to a still limited understanding of the reasons making 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (Spiro-OMeTAD) the state-of-the-art hole-transporting material (HTM) for emerging photovoltaic applications, the molecular tailoring of organic components for perovskite solar cells (PSCs) lacks in solid design criteria. Charge delocalization in radical cationic states can undoubtedly be considered as one of the essential prerequisites for an HTM, but this aspect has been investigated to a relatively minor extent. In marked contrast with the 3-D structure of Spiro-OMeTAD, truxene-based HTMs Trux1 and Trux2 have been employed for the first time in PSCs fabricated with a direct (n-i-p) or inverted (p-i-n) architecture, exhibiting a peculiar behavior with respect to the referential HTM. Notwithstanding the efficient hole extraction from the perovskite layer exhibited by Trux1 and Trux2 in direct configuration devices, their photovoltaic performances were detrimentally affected by th...

TL;DR: In this paper, ultrathin graphite has been applied in hole-conductor-free, fully printable mesoscopic perovskite solar cells as counter electrode to increase the specific surface area of the carbon layer without sacrificing the conductivity.

TL;DR: In this paper, the extrinsic doping properties of CH3NH3PbI3 halide perovskite solar cell materials are investigated by density-functional theory calculations.
Abstract: Approaches for doping organic–inorganic CH3NH3PbI3 halide perovskite solar cell materials are investigated by density-functional theory calculations of the extrinsic doping properties of CH3NH3PbI3. Our results reveal that p-type CH3NH3PbI3 halide perovskites can be realized by incorporation of some group IA, IB, or VIA elements such as Na, K, Rb, Cu, and O at I-rich growth conditions. We further show that n-type CH3NH3PbI3 halide perovskites are more difficult to realize due to the formation of neutral defects or compensation from intrinsic point defects. Our results suggest that nonequilibrium growth conditions and/or processes may be required to produce n-type CH3NH3PbI3 halide perovskites.

Journal ArticleDOI
TL;DR: In this article, a comprehensive environmental impact assessment has been conducted on five typical perovskite solar cells, using an attributional life cycle assessment (LCA) approach, and the results indicate that MAPbI 3 and FAPbI 4 have relatively larger environmental impacts than MASnI 3−x Br x, CsPbBr 3, and MAPBI 2 Cl perovsite cells based on a 1-cm 2 active area solar cell system, and this result can be explained by the different amounts of organic solvents used in the device
