“…As shown in Figure a, the interfacial recombination resistance ( R rec ) of the PSCs can be calculated from the radius of the semicircle in the low‐frequency range. Incomplete semicircle in the high‐frequency range is ascribed to be contact resistance ( R co ) . The enlarge region in high‐frequency range can be found in Figure S10 in the Supporting Information.…”

Inverted planar perovskite solar cells (PSCs) exhibit advantages in terms of simple device fabrication, good reproducibility, and less hysteresis. However, there still remain challenges to passivate the trap states within the perovskite film and reduce interface instability arising from penetration of moisture and the diffusion of metal electrode. In this work, perovskite passivation is reported using gradiently distributed nonfullerene electron-rich Lewis bases small molecule IDIC (a π-conjugated Lewis base: indacenodithiophene endcapped with 1.1-dicyanomethylene-3-indanone), which is realized through an antisolvent dropping process. Additionally, an inorganic wide band gap Ga 2 O 3 is introduced as a tunneling nanolayer into interface between the metal electrode and electron transport layer that effectively passivate interface and mitigate moisture and metal ion diffusion. These treatments enable the fabrication of CH 3 NH 3 PbI 3 -based inverted PSCs with excellent power conversion efficiencies up to 19.86% as well as enhanced ambient stability. This work provides new strategies to improve the performance and stability for the inverted PSCs.

“…MAPbI 3 -NiO composite-based PSCs without encapsulation retained ~90% of its initial PCE for 60 days under ambient environment. [368] XPS and IR analysis showed the existence of Pb-O, C-O, Ni-N and N-NiO bonds, indicating strong chemical interaction between NiO and MAPbI 3 , which leads to the enhanced stability. KCl incorporation also demonstrates significant enhancement of PCE (from 11.40% to 15.08%) and long-term stability (only 16.5% degradation during a period of 50 days store in dark environment, as shown in Fig.…”

Hybrid inorganic-organic perovskites have quickly evolved as a promising group of materials for solar cells and optoelectronic applications mainly owing to the inexpensive materials, relatively simple and versatile fabrication and high power conversion efficiency (PCE). The certified energy conversion efficiency for perovskite solar cell (PSC) has reached above 20%, which is compatible to the current best for commercial applications. However, long-term stabilities of the materials and devices remain to be the biggest challenging issue for realistic implementation of the PSCs. This article discusses the key issues related to the stability of perovskite absorbing layer including crystal structural stability, chemical stability under moisture, oxygen, illumination and interface reaction, effects of electron-transporting materials (ETM), hole-transporting materials (HTM), contact electrodes and preparation conditions. Towards the end, prospective strategies for improving the stability of PSCs are also briefly discussed and summarized. We focus on recent understanding of the stability of materials and devices and our perspectives about the strategies for the stability improvement.

“…There are two regions for Ni2p spectra; one is the Ni2p 3/2 of 851-866 eV, the other is Ni2p 1/2 spin-orbit levels of 870-885 eV. The main peak in the Ni2p 3/2 region at 854 eV is indexed to the Ni 2+ in the Ni-O bonding configuration [23][24][25][26]. While the shoulder peak at 856 eV stems from the Ni 2+ -vacancy induced Ni 3+ ion or excess oxygen from compounds such as oxyhydroxides (NiIIIOOH) [27,28].…”

The sluggish photoelectrochemical performance of p-type dye-sensitized solar cells (p-DSSCs) has hindered its commercial use. In this work, we introduce a novel hierarchical nanocomposite of NiO nanoparticles anchored on highly ordered mesoporous carbons CMK-3 (NiO/CMK-3). Using CMK-3 as a backbone effectively prevented the self-aggregation of NiO nanoparticles and subsequently increased the total specific surface area of the composite for more dye adsorption. The interconnected conductive networks of CMK-3 also served as a split-flow high-speed channel, which was beneficial for hole spin-flow to accelerate hole transfer. The hierarchical NiO/CMK-3 photocathode improved the photovoltaic conversion efficiency to 1.48% in a cell with a Cobalt(II)/(III) electrolyte and a PMI-6T-TPA dye.
