Research

Under the supervision of Huseyin Ayhan Yavasoglu, this experimental study was conducted by Semir Sunkun to investigate the performance variations of flexible photovoltaic modules when integrated into curved vehicle surfaces. A dedicated experimental platform was developed, incorporating an adjustable bending mechanism and a data acquisition system for synchronized monitoring of solar irradiance, ambient temperature, and electrical power parameters. Measurements collected under real outdoor conditions were analyzed using statistical methods to model the effects of curvature on power generation and compare the findings with theoretical approaches. The study was published in Renewable Energy, and further details are available under DOI: 10.1016/j.renene.2026.125557.

Led by Huseyin Ayhan Yavasoglu, with Berke Ogulcan Parlak participating as a scholarship holder, this experimental project was supported by the Scientific and Technological Research Council of Turkiye. The project involved the development of a renewable energy-assisted energy storage system designed for the harsh environmental conditions of Antarctica. The hybrid system, comprising photovoltaic panels, a wind turbine, and energy storage units, was physically installed on Horseshoe Island, Antarctica, and tested under real environmental conditions. The project also included investigating the energy consumption profiles of mobile devices and developing a testing and data acquisition infrastructure for long-term system performance monitoring.

Conducted at the Scientific and Technological Research Council of Turkiye (TUBITAK), this experimental study involved Berke Ogulcan Parlak under the supervision of Huseyin Ayhan Yavasoglu. The study focused on the development and performance assessment of wheel-type caliper sensors used for in-line inspection (ILI) of natural gas and oil pipelines. A modular rotating experimental rig capable of reproducing different geometric deformations was designed and developed, including its mechanical, electronic, and software infrastructure. The system was used to experimentally investigate the measurement performance of caliper sensors under different operating conditions, with particular emphasis on the influence of the initial inspection arm angle on the characterization of concave and convex deformations. The study was published in the Journal of Nondestructive Evaluation, and further details are available under DOI: 10.1007/s10921-026-01337-7.

Conducted at the International Centre for Hydrogen Energy Technologies (ICHET) under the United Nations Industrial Development Organization (UNIDO), this R&D project involved Huseyin Ayhan Yavasoglu as a researcher and project engineer. The project focused on the development of an air-cooled fuel cell system, including electronic design and software development activities. The work aimed to advance hydrogen-based energy conversion technologies and establish the engineering infrastructure required for practical fuel cell system applications.
