Solar energy is one of the most promising renewable energy sources to support the transition toward clean energy, yet conventional solar cell technology still faces efficiency limitations. Perovskite materials offer a potential solution due to their superior optoelectronic properties, although challenges related to stability and toxicity remain. This study aims to analyze the interaction of electromagnetic waves with perovskite materials and to evaluate the effect of nano-scale anti-reflective coatings on improving energy conversion efficiency. The research employed a combination of electromagnetic simulations using specialized software and laboratory experiments with miniature perovskite solar cell prototypes. Simulation results demonstrated higher electromagnetic field intensity within the active layer after the addition of anti-reflective coatings, with photon absorption increased by 15–18%. Experimental validation revealed that the energy conversion efficiency improved from 16.8–17.5% without anti-reflective layers to 20.5–21.3% with TiO₂- and SiO₂-based coatings. Optical characterization using a spectrophotometer confirmed enhanced light absorption up to 90% at specific wavelengths, while SEM analysis showed that smoother and more uniform SiO₂ coatings contributed to superior performance compared to TiO₂. Minor discrepancies between simulation and experimental results were attributed to fabrication variations, yet both approaches exhibited consistent improvement trends. These findings highlight that integrating perovskite materials with nano-scale anti-reflective coatings is a key strategy for enhancing the efficiency of next-generation solar cells while supporting future clean energy sustainability.

Architecture using tree topology has become a popular approach in managing computer networks. Tree topology combines elements of star and bus topologies, resulting in an efficient and scalable network for a variety of purposes. This paper discusses the basic concepts of architecture using tree topology, including hierarchical structures and design advantages. First, the tree topology consists of a parent node (root node) which leads to a number of branch nodes (branch nodes). Each branch node can then connect to other nodes, forming a multilevel hierarchy. In computer networks, this topology is often used to connect a number of LANs (Local Area Networks) into a larger network. The main advantages of tree topology are scalability and management efficiency. The network can be expanded by adding new branch nodes without affecting the rest of the network. Additionally, network monitoring and maintenance becomes more organized due to a clear hierarchical structure. However, tree topology also has disadvantages. If the parent node fails, then all parts of the network connected to that node can be affected. Additionally, complex implementations may require more sophisticated hardware and software. In the modern computing era, tree topologies are used in a variety of contexts, ranging from corporate network infrastructure to online content distribution. Its ability to provide an organized and extensible structure makes it an attractive choice in designing efficient and reliable network architectures.
