Fullerene is one of the most critical materials that are widely used to improve and examine the inverted perovskite solar cells (PSCs, p‐i‐n structure). Fullerenes are known to improve the stability, lower the hysteresis, and increase the power conversion efficiency of the PSCs. Fullerene ...
Doping of perovskite semiconductors1and passivation of their grain boundaries2remain challenging but essential for advancing high-efficiency perovskite solar cells. Particularly, it is crucial to build perovskite/indium tin oxide (ITO) Schottky contact based inverted devices without predepositing a layer ...
"In addressing the core inefficiencies found in inverted perovskite solar cells, which are predominantly due to nonradiative recombination losses, a new standard in solar cell efficiency is being set," said Northwestern professor Mercouri Kanatzidis. "This is a prime illustration of how the field of...
Perovskite solar cells with an inverted architecture provide a key pathway for commercializing this emerging photovoltaic technology because of the better power conversion efficiency and operational stability compared with the normal device structure. Specifically, power conversion efficiencies of the inverted ...
Perovskite solar cells (PSCs) with an inverted structure (often referred to as the p–i–n architecture) are attractive for future commercialization owing to their easily scalable fabrication, reliable operation and compatibility with a wide range of perovskite-based tandem device architectures. However...
Australian scientists have built a perovskite solar cell based on 2D and 3D salts. By adding a fluorinated lead salt in the processing solution – normally..
In a conventional perovskite solar cell, the device architecture constitutes the light-absorbing perovskite layer in a sandwiched configuration between mesoscopic metal oxide such as TiO2, Al2O3, ZnO as electron transport layer (ETL) and organic semiconductors such as tetrakis[N,N-di(4-methoxyphenyl...
2.2. Fabrication of inverted perovskite solar cell (IPSC) The IPSCs were manufactured in a glovebox under a N2 atmosphere and controlled humidity. ITO/NiOxIn was used as substrate to deposit the perovskite (PVK) layer by spin coating. A solution containing 1.2 mmol of PbI2 (99.9985 %, Alfa...
Fullerene derivatives are extensively employed in inverted perovskite solar cells due to their excellent electron extraction capabilities. However, [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) agglomerates easily in solution and exhibits a relativel
Defects at the top and bottom interfaces of three-dimensional (3D) perovskite photoabsorbers diminish the performance and operational stability of perovskite solar cells owing to charge recombination, ion migration and electric-field inhomogeneities1,2,3,4,5. Here we demonstrate that long alkyl amine...
