Improving the Efficiency of Thin-Film Silicon Solar Panels

School of Engineering Entrepreneurship as a driver of the development of a digital educational ecosystem for transport and logistics

“…The theoretical development and practical testing of models and methods of the digital educational ecosystem for the transport and logistics sector is based on the current provisions of the programs of strategic development of the country, its transport and logistics complex, educational system, highlighted in the research of scientists, teachers of the St. Petersburg State University of Railways of Emperor Alexander I [1][2][3][4][5][6][7][8][9]. The research of SEE technologies is directly correlated with the tracks of the University's development until 2030, the provisions of the Priority 2030 project and other important guidelines for the research and educational activities of the PSUREA.…”

“…During the implementation of the innovative educational project "School of Engineering Entrepreneurship", it is planned to achieve the following key results: The SEE of the St. Petersburg State University of Railways of Emperor Alexander I are based on modern principles of innovation in engineering education, the best world practices, proven research, the results of which are published in the latest scientific publications [1][2][3][4][5][6][7][8][9]. The presented directions of functioning, educational technologies and methods of the School of Engineering Entrepreneurship can be considered as a well-formed, but dynamically developing integrated complex of the digital educational ecosystem.…”

Maximum Power Point Tracker Optimization for Phovoltaic Systems based on III-V Elements

“…There are several classifications for photovoltaic cells with a silicon base, such as monocrystalline, polycrystalline, thin film and half cut. These classifications are typically related to the manufacturing process and homogeneity of the silicon layer within the cell arrangement [12,17,27]. Each type of solar panel sharing the same base material has a similar I/V curve and frequency response.…”

“…Based on recent studies, the highest theoretical efficiency rating achievable by photovoltaic modules with silicon base material is 26.1% [27]. Understandably, engineers are trying to increase the efficiency of these modules without modifying their base material [12]. As the maximum theoretical efficiency for silicon cells is defined, researchers and manufacturers are currently working to reduce the thermal variation impact on the cells by increasing the heat transfer of the module [12] and developing new structures for silicon modules with the implementation of Passivated Emitter and Rear Cell (PERC) [6,13,18,25].…”

Monofacial PERC has a silicon base, however, it has back-surface passivation, allowing the reflected solar irradiance to also be harvested by the module.…”
