Quantum dot solar cells (QDSCs) are one of the most optimistic third‐generation solar cells. Because of the superior qualities, such as its size, tuneable bandgap, high stability, and extremely low cost, quantum dots (QDs) have drawn a lot of attention in photovoltaic applications for highly effective solar cells. Herein, WO3 is utilized as the electron transport layer (ETL), MoTe2 as the hole transport layer (HTL), and lead sulfate treated with tetrabutylammonium iodide (PbS‐TBAI) as the QD absorber layer. Overall optimization still represents an obstacle to raise the efficiency of QDSC. Temperature, series–shunt resistance, and absorber layer thickness are optimized, and further analysis is done for overall optimization on the contour plot of electron affinities of HTL and ETL. For all aspects of simulation work, the SCAPS‐1D simulator program is employed. Fill factor 85.96%, open‐circuit voltage 923.7 mV, short‐circuit density 38.61 mA cm−2, and power conversion efficiency 30.66% are the values of the optimized performance parameters. The improved high efficiency of the proposed device can pave for the fabrication of QDSC.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88301567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adsorption reaction is multilayer adsorption, in which chemical adsorption plays a major role. There are also some processes like physical adsorption, liquid phase diffusion, and internal diffusion of particles. The adsorption reaction is exothermic and spontaneous, which is more favorable at low temperatures. During the adsorption process, the entropy value decreases, the degree of disorder and freedom of the solution decreases, and the structure also changes. What's more, H2O2, pH, ribbons's dosage, dye's concentration, and temperature affect the degradation performance of 1K101 on MB. Degradation reactions are mainly controlled by surface chemical reactions, including chemical reduction reactions and adsorption. When c(H2O2) is 15 mm, pH is 2, ribbons’ dosage is 0.9 g, c(MB) is 20 mg L−1, temperature is 338 K, the degradation effect is the best. The optimal conditions with lowest overall cost obtained under the orthogonal experiment are: c(H2O2) = 20 mm, pH = 2, ribbons's dosage = 0.7 g, c(MB) = 20 mg L−1, and T = 338 K. Overall, 1K101 amorphous ribbon can be utilized to treat MB solution, and its degradation effect is better than adsorption effect, which can provide new ideas for the reuse of waste amorphous ribbon and the treatment of azo dye wastewater.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75130385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

X‐ray diffraction analysis results show that cubic magnetite Fe3O4 and hexagonal ZnO phases originate from the core and the shell, respectively. Hexagonal ZnO and cubic magnetite Fe3O4 phases belonging all nanoparticles are confirmed by HR‐TEM benefiting the lattice fringe. All the nanoparticles present superparamagnetic behavior. Under 532 nm excitation, they release the emission in the visible and infrared regions. They exhibit blue–green emission attributed to 2H11/2–4I15/2, 4S3/2–4I15/2 transitions, red emission attributed to 4F9/2–4I15/2 transitions, and infrared emission ascribed to 4F9/2–4I15/2, 2F7/2–2F5/2 transitions. Above the 0.2mol% dopant ratio, the luminescence intensity starts to decrease because of the concentration quenching. The produced nanoparticles are promising for bioimaging and magnetic hyperthermia treatment, due to their magnetic and luminescent properties, orientation to the target area, and their presence in the target area can be determined.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82028847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
