Special Issue Information

Dear Colleagues,

We warmly invite you to submit your work to this Special Issue titled "Advances in Novel Solar Energy Nanomaterials and Technical Applications: 2nd Edition".

Micro- and nanostructured materials have played a fundamental role in the increase in photovoltaic solar cells' efficiency in recent years. Examples include plasmonic enhancement, reflection enhancement, light scattering, and enhanced carrier collection efficiency, among others. One reason for this is that micro- and nanostructures can significantly enhance light harvesting in the near-infrared and infrared regions of the solar spectrum. On the other hand, the incorporation of nanoparticles in solar cells has led to the development of several novel cell concepts with disruptive importance in the PV field, such as perovskite solar cells, quantum dot solar cells, intermediate band solar cells, epitaxial solar cells, nanowire solar cells, organic heterojunction solar cells, dye-sensitized solar cells, quantum dots, and up- and down-converters. Additionally, solution-processed solar cells incorporating nanostructures have improved performance and enabled flexible cells that can be mass-produced via roll-to-roll techniques.

This Special Issue aims to present a comprehensive collection of works on improving the performance of photovoltaic solar cells through the application of micro- and nanostructures and micro/nanomaterials in solar cell fabrication.

In this study, the PV performance of Au/BSF/CTS/CdS/i-ZnO/ITO thin-film solar cell (TFC) structure was systematically investigated using SCAPS-1D software. The effects of several critical parameters, including interface defect density, recombination mechanisms, absorber defect density, operating temperature, parasitic resistances, and different back surface field (BSF) layers, were comprehensively analyzed. The SCAPS-1D software results reveal that the photovoltaic performance is highly sensitive to the defect density at the absorber layer interface. When the interface defect density increased from 1012 cm−3 to 1016 cm−3, the open-circuit voltage (VOC) decreased from approximately 0.68 V to 0.45 V, while the power conversion efficiency (PCE) declined from nearly 19% to about 7%. Similarly, an increase in absorber defect density enhanced the Shockley–Read–Hall recombination rate, thereby reducing carrier lifetime and significantly deteriorating PV parameters. The influence of radiative and Auger recombination (BAuger) processes was also examined, revealing that higher recombination coefficients lead to substantial reductions in current density and efficiency due to increased carrier losses. Furthermore, the impact of parasitic resistances was evaluated, demonstrating that decrease the series resistance from 9.5 Ω·cm2 to 0.5 Ω·cm2 increased the fill factor (FF) from about 48% to nearly 78%, while the device efficiency improved to approximately 32%. In addition to these parameters, particular emphasis was placed on the investigation of different BSF materials to enhance back contact performance. Various BSF layers, including SnS, PbS, V2O5, and Sb2S3, were examined to improve band alignment and suppress minority carrier recombination at the rear interface. Among these materials, the SnS BSF layer provided the most favorable band alignment with the CTS absorber, leading to a notable improvement in PV parameters and increasing the efficiency to approximately 25%. Overall, the results demonstrate that optimizing defect densities, recombination mechanisms, parasitic resistances, and especially the selection of appropriate BSF materials plays a crucial role in improving the performance of CTS-based TFCs.
