“…During the past few years, organic–inorganic hybrid perovskites have received much attention in photovoltaic field for their unique properties, such as efficient light harvesting, long exciton‐diffusion length, small band gap, high‐carrier mobility, etc . The remarkable photoelectric conversion efficiency (PCE) of perovskite solar cells (PSCs) over 23% have been achieved since the application of solid‐state hole transport material (HTM) . In PSCs, HTMs play a significant role in facilitating hole extraction and migration, preventing internal charge recombination and enhancing stability .…”

Four carbazole-triphenylamine hole transporting materials (HTMs) with a pyridine or benzene on the N of carbazole have been designed and developed. The molecular structures on their photophysical, electrochemical, thermal, as well as photovoltaic properties in perovskite solar cells (PSCs) are comprehensively analyzed. It is noted that the pyridine-contained compounds show bathochromic spectra response, slightly lower HOMO level, and higher thermal stability than their benzene-contained counterparts. Photoluminescence study indicates that the molecule with a pyridine unit possess better hole extraction properties on the perovskite/HTM interface. When used in PSCs, pyridine-contained HTMs exhibit higher efficiency and better stability than benzene-contained HTMs. Moreover, the PSCs based on the pyridinecontained HTM exhibit a promising power conversion efficiency of 18.45% with good light-soaking and long-term stability, which is even better than that of conventional spiro-OMeTAD under the same conditions. Therefore, the results provide a promising strategy to design and develop novel HTM molecules for efficient and stable PSCs.

“…Replacement of the MA-ions either partially or fully with a suitable ion size at the A site will change it toward a symmetrical lattice structure, which will improve the stability. 49 The mixture strategy and the change of component at the A site, such as using a mixture of MA and formamidinium (FA) as well as the cations with acetamidinium (Ace) and MA, can deliver a high PCE of 19.5% and a promoted device stability. The substitution of larger Ace cations induced distortion of the lattice cubic structure with a changed tolerance factor.…”

“…ETMs such as SnO 2 , TiO 2 , ZnO, PCBM, C-60, etc. have been researched due to its ability to increase the cell performance significantly by collecting electrons more efficiently and reducing electron-hole recombination at the absorber/ETM interface [42,43]. The most common metal-oxide ETM for high-performance PSCs are mesoporous and planar TiO 2 .…”

In recent years, organic-inorganic hybrid perovskite solar cells (PSCs) have received more and more attention due to their high photovoltaic (PV) performance, potentially high efficiency, simple cost-effective, scalable, and vacuum-free fabrication techniques. Concerned, but there are still stability issues in PSCs. The use of inorganic materials as photogenerated carrier transport layers can enhance the stability of PSC. In this report, we designed a PSC model with a novel npp+ heterojunction cell structure of Al/ITO/BaSnO3 /CH3NH3 PbI3 /Cu2O/(Cu or Mo) and analyzed the structure by varying the thickness and carrier concentration of each constituent layer, working temperature, and back-contact metal work function using SCAPS-1D solar cell simulator. The simulation addresses, in particular, the role of the BaSnO3 as electron transport materials (ETM) and Cu2O as hole transport materials (HTM) for the device performance. Using BaSnO3 and Cu2O as ETM and HTM, respectively, this article presents the optimization of cell parameters to improve device performance with a predicted power conversion efficiency (PCE) of 32% for the modeled PSC. The proposed novel structure for PSC showed very good PV performance stability on elevated temperature with the temperature coefficient of PCE of only - 0.112 %K-1.
