Impact of Cation Substitution in (Ag_xCu_1−x)₂ZnSnSe₄ Absorber‐Based Solar Cells toward 10% Efficiency: Experimental and Theoretical Analyses

Solar RRL (2021)

Shaham Quadir Mohammad Qorbani Ying-Ren Lai Amr Sabbah Ho–Thi Thong

Partial Cation Substitution In article number 2100441, Cheng–Ying Chen, Kuei–Hsien Chen, Li–Chyong Chen, and co-workers of the National Taiwan University showed the impact of partial cation substitution in a (AgxCu1-x)2ZnSnSe4 absorber-based solar cell. Based on the experimental and theoretical studies, the enhanced photovoltaic efficiency (> 10%) can be attributed to the shallower de-fect states in the Ag-alloyed kesterite material.

Selecting Support Layer for Electrodeposited Efficient Cobalt Oxide/Hydroxide Nanoflakes to Split Water

ACS Sustainable Chemistry & Engineering (2016)

Naimeh Naseri Ali Esfandiar Mohammad Qorbani Alireza Z. Moshfegh

Energy and environment crises motivated scientists to develop sustainable, renewable, and clean energy resources mainly based on solar hydrogen. For this purpose, one main challenge is the low cost flexible substrates for designing earth abundant efficient cocatalysts to reduce required water oxidation overpotential. Here, a systematic morphological and electrochemical study has been reported for cobalt oxide/hydroxide nanoflakes simply electrodeposited on four different commercially available substrates, titanium, copper sheet, steel mesh, and nickel foam. Remarkable dependence between the used substrate, morphology, and electrocatalytic properties of nanoflakes introduced flexible porous steel layer as the best substrate for samples with 499 mV overpotential, 5.3 Ω charge transfer resistance, and 0.03 S–1 turnover frequency. Besides, carbonaceous paste including carbon nanotubes and graphene sheets as the middle layer increased turnover frequency by 33%, effective surface interface nearly three times while it reduced 7.5% of resistance. Hence, optimizing the conductive nanostructured paste can lead to more efficient cobalt electrocatalysts exposing more active atomic surface sites.

Short- and Long-Range Cation Disorder in (Ag_xCu_1–x)₂ZnSnSe₄ Kesterites

Chemistry of Materials (2022)

Shaham Quadir Mohammad Qorbani Amr Sabbah Tai‐Sing Wu Aswin kumar Anbalagan

Understanding the nature of and controlling the cation disorder in kesterite-based absorber materials remain a crucial challenge for improving their photovoltaic (PV) performances. Herein, the combination of neutron diffraction and synchrotron-based X-ray absorption techniques was implemented to investigate the relationships among cation disorder, defect concentration, overall long-range crystallographic order, and local atomic-scale structure for (AgxCu1–x)2ZnSnSe4 (ACZTSe) material. The joint Rietveld refinement technique was used to directly reveal the effect of cation substitution and quantify the concentration of defects in Ag-alloyed stoichiometric and nonstoichiometric Cu2ZnSnSe4 (CZTSe). The results showed that 10%-Ag-alloyed nonstoichiometric ACZTSe had the lowest concentration of detrimental antisite CuZn defects (∼8 × 1019 defects per cm–3), which was two times lower than pristine and five times lower than the stoichiometric compositions. Moreover, Ag incorporation maintained the concentrations of beneficial Cu vacancies (VCu) and antisite ZnCu defects to >2 × 1020 defects per cm–3. X-ray absorption measurements were performed to verify the degree of disorder through the changes in bond length and coordination number. Therefore, the incorporation of Ag into the CZTSe lattice could control the distribution of antisite defects, in the form of short- and long-range site disorder. This study paves the way to systematically understand and further improve the properties of kesterite-based materials for different energy applications.

To What Extent Can Surface Morphology Influence the Photoelectrochemical Performance of Au:WO₃ Electrodes?

The Journal of Physical Chemistry C (2014)

Naimeh Naseri Mohammad Qorbani Hyoung–il Kim Wonyong Choi Alireza Z. Moshfegh

Considering hydrogen as a future fuel, development of clean energy sources based on solar power is the main human challenge in recent years. Here, for the first time, Au:WO3 photoanodes are synthesized with different Au concentrations and then applied for photoelectrochemical (PEC) water splitting. A comprehensive statistical study on the prepared photoanode surface is conducted to understand the correlation between surface morphology and PEC activity, using atomic force microscopy (AFM). The results clearly justified the maximum surface area observed for the film containing 1 mol % Au. Additionally, X-ray diffraction (XRD) analysis determined that Au nanocrystals have been formed in cubic structure with the size of 29–52 nm. X-ray photoelectron spectroscopy (XPS) revealed that the presence of Au in a combined metal/oxide state strongly affects on the Au:WO3 photoanode performance. Photoresponse investigation of the synthesized films showed that the highest photocurrent was obtained for the sample containing 1 mol % gold with the maximum incident photon to current efficiency (IPCE) of about 20% at 360 nm wavelength. In addition, measuring the amount of hydrogen produced in the water splitting reaction supports the result that the sample containing 1 mol % Au exhibits the highest hydrogen production rate (∼3 μmol/h) as compared to other samples.
