Factors influencing halide vacancy transport in perovskite solar cells
<p>Python code will generate high grid structures in CsPbX<sub>3</sub> (X=Cl, Br, I) and a migration path. It will collect the data from a customized number of grids and calculate the migration barrier. Various factors, such as defect charge states or pressure, can be applied to high grid structures to consider device-like conditions. Examples of CsPbI<sub>3</sub> high grid structures are named by {#of grids}_{grid point x}_{grid point y}.</p>

A combined experimental and theoretical approach to the electronic and magnetic properties of Cu-doped LaMnO3 perovskites
<p>Collected data in Origin file format of magnetic and cw-EPR measurements of LaMnO3, La2CuO4 and Cu-doped LaMnO3. Temperature and magnetic field dependent magnetization measurements have been carried out on a Quantum Design Physical Properties Measurement System (PPMS). Room temperature continuous wave EPR (cw-EPR) measurements at X-band (9.86 GHz) frequencies have been conducted with a Bruker B-ER420 spectrometer upgraded with Bruker ECS 041XG microwave bridge and a lock-in amplifier (Bruker ER023M) using Bruker TE102 resonator applying a modulation amplitude of 5 G, a modulation frequency of 100 kHz and an attenuation of 20 dB for the microwave bridge. The samples have been measured in quartz tubes of 2.9 mm outer diameter with a filling height of approx. 9 mm containing approx. 7 mg to 20 mg of the powdered sample. All spectra are background-corrected taking an empty quartz tube as reference.</p>

Perovskite modified catalysts with improved coke resistance for steam reforming of glycerol to renewable hydrogen fuel
<p>Catalytic steam reforming of renewable<span> feedstock to renewable energy or chemicals always goes with intense coking activities that produce carbonaceous products leading to low performance and eventual catalyst deactivation. A supported</span> metal catalyst such as Ni/Al<sub>2</sub>O<sub>3</sub> is known to catalyse gasification and decomposition of biomass feedstock largely for renewable fuel production with promising results. Catalyst deactivation from high carbon deposition, agglomeration, and phase transformations resulting in rapid deactivation are some of the issues identified with the use of the catalyst. In this work, improvement on the coke resistance and catalytic properties of the Ni/Al<sub>2</sub>O<sub>3</sub> catalyst is sought via the use of a thermally stable and coke-resistant perovskite La<sub>0.75</sub>Sr<sub>0.25</sub>Cr<sub>0.5</sub>Mn<sub>0.5</sub>O<sub>3-δ</sub> (LSCM) as catalyst promoter/modifier and involving Zirconia-doped Ceria (Ce-Zr) as alternative support in steam reforming of pure and by-product glycerol. The stabilizing influence of the LSCM on the Ni catalyst has improved stability against agents of deactivation with a significant improvement of catalytic activity of Ni/Al<sub>2</sub>O<sub>3</sub> in H<sub>2</sub> production and robust suppression of carbon deposition. Particularly, the synergy between the LSCM promoter and alternative Ce<sub>0.75</sub>Zr<sub>0.25</sub>O<sub>2</sub> support enhanced the basic and redox properties known for Ce<sub>0.75</sub>Zr<sub>0.25</sub>O<sub>2</sub> support in contrast to the weak acid centres in the γ-Al<sub>2</sub>O<sub>3</sub> support which further improved nickel stability, catalyst-support interaction with a resultant high catalytic activity, and robust coke suppression as a result of enhanced oxygen mobility. There is a correlation between the product distribution, nature of coke deposited, and reforming temperature, as well as the type of support and structural modification. Hence, the integration of a robust perovskite material as a catalyst promoter and choice of support could be tailored in the design and development of robust catalyst systems to improve the performance of supported metal catalysts particularly the suppression of carbon deposition for hydrocarbon and biomass conversion to renewable fuel or chemicals.</p>
Boosting efficiency of eco-friendly perovskite solar cell through optimization of novel charge transport layers
<p>Formamidinium tin triiodide (FASnI<sub>3</sub>)is a suitable candidate for the absorber layer in perovskite solar cells (PSC) because of its non-toxicity, narrow band gap, thermal stability,y and high carrier mobility. This study focuses on the analysis and improvement in the performance of FASnI<sub>3</sub>-based PSCs using various inorganic charge transport materials; copper-based materials such as Cu<sub>2</sub>O, CuAlO<sub>2</sub>, CuSCN and CuSbS<sub>2</sub> are introduced as hole transport layers due to their earth abundancy, ease in manufacturing, high charge mobilities and chemical stability. Similarly, fullerene derivates (PCBM and C<sub>60</sub>) are deployed as electron transport layers due to their mechanical strength, thermal conductivity and stability. The effect of these materials on the optical absorption, quantum efficiency, energy band alignment, band offsets, electric field and recombination are studied in detail. The reasons for low performance of the cell are identified and improved through design optimization. The PSC performance is analyzed in both inverted and non-inverted architecture. Among all the structures, the best result is achieved through ITO/CuSCN/FASnI<sub>3</sub>/C<sub>60</sub>/Al with an efficiency of 27.26%, Voc of 1.08 V, Jsc of 29.5 mA/cm<sup>2</sup>, and FF of 85.6%.</p>
