How holes are generated due to Sn2 to Sn4 oxidation reaction in perovskite? 


Best insight from top research papers

Holes are generated due to the Sn2+ to Sn4+ oxidation reaction in perovskite materials . The oxidation of Sn2+ to Sn4+ is a degradation pathway that occurs in Sn-based perovskites . This oxidation reaction is known to occur under atmospheric oxygen . The presence of oxygen vacancies in the SnO2 electron transport layer (ETL) also contributes to the generation of holes . To mitigate this issue, passivation methods have been explored, such as introducing ammonium sulfide [(NH4)2S] to the SnO2 precursor to terminate the Sn dangling bonds and reduce surface traps . Additionally, the addition of SnF2 has been found to suppress the Sn2+ to Sn4+ oxidation reaction and improve the performance of Sn halide perovskite-based devices .

How does the spin-orbit coupling affect the band gap of perovskites?5 answersSpin-orbit coupling (SOC) has a significant impact on the band gap of perovskites. In two-dimensional hybrid organic-inorganic perovskites, the spin splitting induced by SOC depends on the arrangement of organic motifs and the orientation of the organic spacer molecules. SOC opens a gap between the valence and conduction bands in perovskites A3SnO (A = Ca, Sr, Ba), resulting in narrow direct band gaps. The accurate calculation of the band gap in halide perovskites using density functional theory (DFT) requires the inclusion of SOC effects, especially for Pb-containing compounds. SOC in lead halide perovskites reduces non-radiative electron-hole recombination by reshaping the electron and hole wave functions and causing spin mismatch. In two-dimensional halide perovskites, SOC significantly lowers the band gaps in certain intramolecular band alignments, while having a negligible effect in others.
How does pinholes come in perovskite?4 answersPinholes in perovskite films can occur due to various reasons. In some cases, pinholes are formed in the electron selective layer (ESL) of perovskite solar cells when there are morphological defects. However, it has been observed that pinholes in the absorber film of carbon-based, all-inorganic perovskite solar cells do not necessarily degrade the cell performance, especially when the film is relatively thick. Pinholes can also be eliminated or reduced by introducing small amounts of CsI in the perovskite layer, resulting in a pinhole-free film with enhanced device performance. Another method to promote grain growth and heal pinholes in perovskite films is by using solvent-extraction and water vapor modulated post-annealing, which leads to high-quality pinhole-free films with large crystalline grains. Additionally, a method involving spin-coating and the use of a co-solvent has been proposed to obtain homogeneous dense pinhole-free perovskite films.
What are the anti oxidants used for inorganic perovskite solar cells?5 answersStrong oxidants, such as tris[2‐((1H‐pyrazol‐1‐yl)‐4‐tert‐butylpyridine)cobalt(III)tris(bis(trifluoromethylsulfonyl)imide)] (FK209) and Na2S2O8, are used to stabilize the main frame structure of inorganic perovskite solar cells. These oxidants strengthen the interaction between the central Pb atom and coordination I atoms, increasing the power conversion efficiency and stability of the doped devices. The use of strong oxidants is a promising approach to inhibit the oxidation of Sn2+ in tin-based perovskite solar cells, improving their stability and performance.
What are the challenges in using HTL/Hole/Charge Transport materials in Slot die Perovskite Solar Cell?4 answersThe challenges in using HTL/Hole/Charge Transport materials in slot die perovskite solar cells include the complexity and cost of synthesis for small molecule-based organic semiconductors like Spiro-OMeTAD, which hinders large-scale printing. Inorganic hole transport materials (HTMs) are being studied as an alternative due to their ease of fabrication, cost-effectiveness, and improved economic feasibility. However, the stability issue of perovskite solar cells still restricts their commercialization. Efforts have been made to improve stability by using inorganic HTMs, which have excellent stability compared to traditional organic HTMs. Additionally, the design and fabrication of high-performance inverted perovskite solar cells (inverted-PSCs) based on diverse HTMs have been explored, along with interface and additive engineering to suppress nonradiative recombination. The challenges and research pathways for facilitating the industrialization of inverted-PSCs have also been discussed.
In perovskite solar cell must have both electron transport layer and hole transport layer?5 answersPerovskite solar cells typically require both an electron transport layer (ETL) and a hole transport layer (HTL) for optimal performance. The ETL helps to transport electrons from the perovskite absorber layer to the electrode, while the HTL facilitates the movement of holes in the opposite direction. The choice of materials for these layers can significantly impact the device's efficiency. For example, in one study, the use of double HTLs of CuI/MoO3 was found to improve device performance significantly. Another study compared ZnO and TiO2 as electron collectors and found that both materials could be used effectively in a Sn-based perovskite solar cell. Similarly, the design of efficient electron and hole transport layers was investigated in a study on non-toxic FACsSnI3 perovskite solar cells. Additionally, the influence of different HTL and ETL materials on the performance of a CsSn0.5Ge0.5I3 based perovskite solar cell was examined, with WS2 identified as an optimized ETL. Overall, the presence of both an ETL and HTL is crucial for the efficient operation of perovskite solar cells.
