要旨

Perovskite solar cells (PSCs) are expected to be a part of the next-generation photovoltaic technology owing to their low-cost fabrication process as well as a power conversion efficiency (PCE) that is comparable to that of conventional Si-based solar cells. The quality of a perovskite film is critical for the performance of the resultant PSCs, which can be optimized by a delicate processing control. Herein, we present a unique strategy to modulate the crystal growth of perovskite films by introducing a low-cost and environment-friendly additive, GlyHCl, which leads to the selective growth of the (001) facet and an elongated carrier lifetime, and consequently enhances the photovoltaic performance of the device fabricated with the perovskite films. In addition, PEAI is introduced as a co-additive to passivate the defects in the bulk of the perovskite films. The convenient co-additive strategy results in the highest PCE of 23.8% for inverted PSCs, accompanied by a substantial improvement in device stability.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive. Artificial photosynthesis Batteries Carbon dioxide conversion Catalysis Fuel cells Gas capture/separation/storage Green/sustainable materials Hydrogen generation Hydrogen storage Photocatalysis Photovoltaics Self-cleaning materials Self-healing materials Sensors Supercapacitors Thermoelectrics Water splitting Water treatment
