Fluorine-induced surface modification to obtain stable and low energy loss zinc oxide/perovskite interface for photovoltaic application

Enhanced comprehensive performance of carbon-based hole-transport-layer-free CsPbI2Br solar cells by a low-cost and stable long chain polymer

“…The evident shift of the Pb 4f 5/2 and 4f 7/2 signals to low binding energy for the ABSadded CsPbI 2 Br layer experimentally reveals the interaction of ABS with Pb in CsPbI 2 Br. [46][47][48] It is worth noting that there also exist two weak signals around 141.36 and 136.41 eV for the pristine CsPbI 2 Br layer, corresponding to the surface-uncoordinated Pb atoms (i.e., Pb 0 ). As a deep-level defect, Pb 0 leads to severe nonradiative recombination accordingly.…”

NiOx/PANI nanocomposite doped carbon paste as electrode for long-term stable and highly efficient perovskite solar cells

“…Photovoltaic devices are recognized as an innovative energy source. Current solar cell generations that utilize solution-based methods, such as organic, dye-sensitized, quantum dot, and perovskitebased technologies, [1][2][3][4] have made signicant advances in recent years compared to traditional silicon-and thin-lm-based solar cells. 5,6 Metal halide perovskite solar cells have been extensively studied, have shown considerable performance improvements, and are the subject of further commercial investigation.…”

Isolating the Oxygen Adsorption Defects on Sputtered Tin Oxide for Efficient Perovskite Solar Cells

“…55−57 Additionally, traditional passivation strategies usually have little effect on these oxygenrelated defects located on the surface of sp-SnO 2 . 58,59 Therefore, to improve the PCE of PSCs based on sp-SnO 2 , it is crucial to reduce the influence of these surface states on sp-SnO 2 on the devices. Herein, we propose an isolation strategy to reduce the interfacial recombination.…”

“…sp-SnO 2 has complex surface states, such as oxygen-related defects due to the momentum exchange principle of the magnetron sputtering. These defect states act as SRH recombination sites, ultimately leading to non-radiative recombination at the interface. − Additionally, traditional passivation strategies usually have little effect on these oxygen-related defects located on the surface of sp-SnO 2 . , Therefore, to improve the PCE of PSCs based on sp-SnO 2 , it is crucial to reduce the influence of these surface states on sp-SnO 2 on the devices.…”
