Mrs. Cinar presented a valuable seminar in our department about

Optimization and Characterization Perovskite Solar Cells through Numerical and Experimental Layer Synthesis using various Techniques.  On 19/12/2024.

She delivered a pre-viva seminar as part of her PhD program and discussed the significance of her research with the audience as follows:

The perovskite solar cell is a remarkable efficiency has the potential to greatly the benefit humanity and the methyl ammonium tin chloride (CH₃NH₃SnCl₃) has been utilized in this context as the absorber materials to reduce toxicity. Furthermore, experimentally, the investigation of SnO₂ thin films as ETL is of considerable interest owing to their distinctive and appealing characteristics, including excellent optical transmittance, uniformity, non-toxicity, elevated conductivity, chemical inertness, resistance to thermal degradation, mechanical reliability, piezoelectric capabilities, and cost-effectiveness. Copper plays an essential role in reducing nanocrystalline SnO₂ particle sizes. In addition, the solvo-thermal technique is more impressive than co-precipitation in the synthesis of tin oxide nanostructure. The Cu-doped SnO₂ using the solvo thermal technique had a higher current density and an open circuit voltage. It also had a higher power conversion efficiency when the sun simulator was the same. As well as, the performance of perovskite solar cells by using SCAPS-1D software was improved, using SnO₂ as electron transport layers (ETLs) and records the highest potential to achieve high energy conversion (η) when combined with Spiro-OMeTAD as the HTLs. This development to enhance the performance of environmentally friendly lead-free solar cells using tin-based perovskite materials.
