2.2 The Halide Perovskite (HP) and MXene:H3pp Heterojunction (HP/MXene:H3pp) The fabrication of the HP/MXene:H3pp heterojunction was made by spin coating a solution of the MXene:H3pp on top of the Rb 0.05 Cs 0.05 MA 0.15 FA 0.75 Pb(I 0.95 Br 0.05) 3 quadruple perovskite thin film layer. The as-prepared HP/MXene:H3pp heterojunction
In this work, functionalized 2D titanium carbide (Ti 3 C 2) MXene is employed in normal PSC configuration, at the interface between the halide perovskite and the hole transport layer. The functionalization of the Ti 3 C 2 MXene is made utilizing the same organic additive passivating the halide perovskite layer.
Examining our base technologies which realize 22.2%-conversion efficiency perovskite single junction solar cell module and 26%-heterojunction back-contact solar cells, we clarified that the based technologies were ready to realize 30%-conversion efficiency 4T perovskite/heterojunction crystalline Si tandem solar cells with approximately quarter size of
2 天之前· One functional method to avoid this drawback is to design heterojunction configurations that contain different perovskite materials stacked on top of each other.

By tailoring the composition of buried buffer 3D perovskite, a controllable compressive strain is applied to the upper photoactive 3D perovskite, alleviating its residual tensile stress. We demonstrate that this strained heterostructure promotes the preferred crystal growth, reduces interfacial defect-induced recombination, and
Then, based on the high-temperature resistance of the all-inorganic perovskite battery, the stability and long-term effect of the perovskite battery at high temperatures were studied. Lastly, it is determined that the device not only maintains the high efficiency of PCE = 14.02 %, but also the FF = 70.66 % of the device at 340 K. Consequently, this work may

In this work, we propose an ultrathick solution-processed FAPbI 3 (FA: formamidinium)/MAPbI 3 (MA: methylammonium) bilayer for efficient solar cells without TLs, which only consists of two perovskites sandwiched between two electrodes.
Creating and retaining such an abrupt perovskite/perovskite heterojunction is challenging due to the MHPs'' low formation enthalpy, their solubility, and high ionic mobility. It is therefore very difficult to fabricate a heterojunction through sequential solvent-based deposition of two or more perovskites, as subsequent layer deposition results in re-dissolution of the

Although ZnO has high electron mobility, ZnO NRs arrays have the ability to increase light absorption and provide direct electron extraction channels, making them ideal materials for electron transport layers. 130-132 However, due to the poor chemical compatibility between ZnO and perovskite layer, the stability based on ZnO is relatively poor. 133, 134
Structure engineering of two-dimensional perovskites by the bulky cations can impair the robustness of perovskite heterojunctions.
The methyl ammonium (MA) in the perovskite is organic in nature 16. The low conductivity causes heat to build up in the bulk of the material, which in turn degrades the MA rapidly, leading to the collapse of the perovskite crystal structure 17. This causes the leakage of lead (Pb) into the surrounding environment which is toxic in nature.
Here, we propose an elaborate regulation of the perovskite structural evolution and residual strains by constructing a vertically 3D/3D strained heterostructure (SHS) at the buried interface. Strain management can improve film quality by promoting the desired conformal crystal growth and suppressing defect formation.
The thickness of the perovskite material has a significant impact on the PV properties of the PSC, such as photo generation, carrier transport, and charge collection within the cells.
Regulating residual strain would impact the crystallization behavior of the perovskite film, 45,46 which is critical for the film quality deposited on fully textured c-Si cells. The enhanced intensities of (001) and (002) diffraction signal for the SHS sample also imply improved crystallinity and orientation (Figure S4).
The perovskite film under the non-strained growth exhibits dense and uniform morphology on the pyramids (Figure 4 B). From the PL mapping, we discovered large-scale homogeneity in the perovskite top cell after the formation of SHS (Figure 4 C).
